Product Spotlight: YOKE Rigging Hardware 

Concerned about price, quality & reliability? Choose YOKE, and get all three without making a sacrifice. YOKE swivels are manufactured with the highest grade materials, and are zinc-plated for corrosion resistance and a long life.

WHY USE SWIVEL HOOKS?

Swivel hooks come in two varieties. These are:

  • Positioning Hooks allow the rigger to align the hook while connecting to the load. These hooks aren’t meant to rotate while under load, only to position the hook to the pick point.
  • True Swivel Hooks with Bushings allow the hook to rotate freely under the load, while the top coupling/fitting pivots to let the load rotate. This helps prevents your line twisting.

Swivels should be used when the lift deals with these issues:

  • Swivels reduce bending loads on rigging attachments to allow the load to position itself freely.
  • Swivels should be used in place of shackles during applications where the shackle might twist and might be haphazardly loaded.

FYI: Before you lift a load, make sure there are not cracks or defects in the hook or latch, and that the chain or wire rope is not worn, and in good working order. Not all hooks are meant to overhead lift and not all swivels are meant to swivel under-load—It’s important to know which application the one you use is meant for.

WHICH INDUSTRIES USE YOKE SWIVEL SELF-LOCKING HOOKS?

Swivel self-locking hooks should only be used to swivel under-load if they’re fit with a bearing and are approved by the manufacturer overhead lifting. Swivel self-locking hooks are generally known as positioning hooks, since they rotate which makes connecting the rigging to the load much easier.

Industries that use YOKE Swivel Self-Locking Hooks, include:

  • Automotive
  • Construction
  • Mining
  • Manufacturing
  • Machining
  • Transportation

Get Hooked: All About Clevis Grab & Slip Hooks, Eye Hooks & More 

We’re hooked on hooks at Hercules SLR!

There are many different hooks used for towing, pulling, securing, lifting and rigging, and each type of hook comes with different openings, latches, sizes and more. Hooks are often used to create sling assemblies (particularly with chain), and are also used in various transport applications.

It can be difficult to remember them and what they’re used for, so Hercules SLR wants to make it easy—We’ve made this comprehensive hook guide to secure your hook know-all.

This hook guide will cover topics like what is a below-the-hook lifting device, some of the most often-used hooks for securing and rigging, including non-overhead hooks, overhead lifting hooks, transportation hooks, what the different hook & chain ‘grades’ mean, plus tips for maintenance, inspection, ASME hook standards, and more.

Ready to get hooked on rigging? Read on! 

What Exactly is a Below-the-Hook Lifting Device?

A below-the-hook lifting device is ‘any device used to connect a load to a hoist. The device may contain components such as slings, hooks, and rigging hardware…” A below-the-hook lifting device is a piece of equipment connected to a crane or other lifting device which grabs an item so it can be moved or secured to different place.

To that end, you might think that cranes and other lifting decides are known as “above-the-hook” lifting devices, however, they’re more often referred to as ‘overhead lifting devices’, and are rarely referred to as above-the-hook.

Clevis & Eye Hooks: What’s the Difference?

A clevis hook refers to a hook with a U-shaped attachment point or coupling with holes to thread a pin through and assemble your rigging—Many people like the removable pin to assemble and disassemble rigging quickly & easily. Clevis hooks are used for non-overhead applications.

You’ll likely hear the term ‘clevis’ used to describe other metal pieces of hardware with a clevis coupling. Hooks with clevis attachments can also be used for overhead lifts in many cases (Remember, they’ll be marked as Grade 80 or higher).

An eye hook (non-cradle grab & slip hook) is also used for non-overhead lifts, and is often used with tie-down equipment.

So, what’s the difference between eye hooks and clevis hooks? The attachment point/coupling. An eye hook has a rounded attachment point/coupling, unlike a clevis hook, which comes with a cotter pin to thread through the hole. Both can be used for overhead lifting, but are also often found alongside transportation securing and rigging set-ups.

Non-Overhead Lifting

Transportation 

Grade 70 chain and hooks are typically used to secure loads for transportation applications. Grade 80 is being used more often, however Grade 70 continues to be a popular choice for securement.

Overhead Lifting

Securing, Lifting & Rigging

Rigging hardware is used to attach a load to the lifting point of a crane, and hooks are among some of the most popular rigging hardware.

EYE HOOK

  • There can be different kinds of eye hooks—Hooks typically are eye or clevis hooks, which refers to the hook’s point of attachment.

CLEVIS HOOK

  • A hook with a clevis coupling or attachment point (see above).

SWIVEL HOOK

  • A hook with a swiveling coupling or attachment point.

EYE/ EYE HOIST HOOK

  • Available in both carbon and alloy steel.

FOUNDRY HOOK

  • A foundry hook is a type of grab hook.

GRAB HOOK

  • A grab hook does not usually feature a safety latch. It’s important to note that like clevis and grab hooks, other types of hooks can be grab hooks. For example, foundry hooks are a type of grab hook.

SLIP HOOK

  • A slip hook has a wider throat than a grab hook, and does feature a safety latch.*

SORTING HOOKS

  • Sorting hooks have wide throat openings, which taper to a narrower basket. They have a slightly sharper tip than other hooks, and are used to quickly grab objects to lift. These are normally used in pairs, on steep angles.

* Safety latches are used to make sure the load stays connected under slack conditions. They’re not load-rated, and should never be placed under a Herculesload. Use hook latches unless unsafe to do so.

Hook Maintenance

When Should a Hook be Removed from Service?

According to ASME B30.10 standards, hooks should be removed from service when they are:

  • Missing/illegible hook manufacturer’s identification or secondary identification
  • Missing and/or illegible rated load identification
  • Excessive pitting or corrosion
  • Cracks, damage and/or gouges
  • Any wear that exceeds 10% (or as recommended by the manufacturer) of the original section dimension of the hook or its load pin
  • Any visible deformations—This includes any bends, twists or other abnormalities from the plane of the unbent hook
  • Any distortion that causes an increase in the throat opening of 5%, not to exceed 1/4″ (6mm), or as recommended by the manufacturer.
  •  Inability to lock or latch—If a hook has a safety latch, it must be able to close properly, or any self-locking hook that doesn’t lock.
  • Damage, missing or malfunctioning hook attachment and securing means

Hooks should be inspected before, during and after use by the user. Rigging hooks should also be inspected periodically, or as recommended by the manufacturer.

Non-destructive testing is often used to determine if there are defects, nicks, gouges or any other deformations in metal gear or hardware, like hooks.

Grade 70, 80, 100—What do they all mean?

When we talk about ‘grade’ in relation to hooks, we actually refer to the grade of the chain that will be used with the hook. Grade refers to the tensile or breaking strength of chain.

Sound good? Let’s get into it:

GRADE 70
Grade 70 chain
Grade 70 Chain.

NAME: Grade 70

PROPERTIES: Heat-treated carbon chain

INDUSTRIES: Transportation

APPLICATIONS: Use as a tie-down chain or transportation lashing.

DON’T DO THIS: Grade 70 chain is not meant for overhead lifting—Only use Grade 70 chain and hooks for tie-down and lashing applications.

FUN FACTS: You’ll likely hear Grade 70 chain called ‘trucker’s chain’. It usually has a gold-chromate coating that helps it resist corrosion, since their load is continuously exposed to the outdoor elements and things like salt from the highway also reduce their effectiveness. The gold colour also helps it remain visible for truckers.


GRADE 80

NAME: Grade 80

PROPERTIES: Heat-treated steel chain

INDUSTRIES: Rigging, material handling & some transportation.

APPLICATIONS: Grade 80 chain is the minimum grade for overhead lifts, and is also often used in applications like recovery, safety & towing. Grade 80 chain is also often used with hooks in transport for flat-bed trucking to secure heavy loads.

DON’T DO THIS: Don’t use Grade 80 chain and hooks that are specifically marked for tie-down application in an overhead lifting capacity. (Hercules SLR’s Overhead Lifting Chain is meant for overhead lifting applications).

FUN FACTS: Will have 8 or 800 to denote that it is a Grade 100 chain or hook. 


GRADE 100  

NAME: Grade 100

PROPERTIES: Alloy-steel chain

INDUSTRIES: Rigging & lifting—Mining, offshore, construction, material handling & maritime

APPLICATIONS: Sling component, popular for overhead lifts.

DON’T DO THIS: Use any hook to rig with—Use at least a Grade 100 hook with chain.

FUN FACTS: Will have 10 or 100 to denote that it is a Grade 100 chain or hook.


The More you Know

  • These are some of the most commonly-found hooks in rigging—Some unconventional, or less-commonly found hooks include foundry, claw, bucket, ‘S’ hooks, alloy-swivel, plate & sorting hooks. 
  • Lifting hooks are constructed with a minimum 5:1 safety factor.
  • Hooks should have a latch, or safety latch to connect the throat opening. This prevents load lines from disconnecting. Some overhead lifting devices may not have a safety latch or may have additional features that make using the latch impractical.
  • NDT or non-destructive testing is a good way to check for deformities and defects in metal gear like hooks. We can find abnormalities on the inside and the outside of your metal gear.
  • The load hook should be the weakest part of the lifting equipment.
  • The hook tip should point out, away from the load, with no slack present so the hook won’t tip-load.

Lifting Out of this World: Hercules SLR Helps RADARSAT Constellation Mission

Hercules SLR is committed to safety at every level—Even in outer space.

On Wednesday, June 12, SpaceX launched the RADARSAT Constellation Mission from Space Launch Complex 4E (SLC-4E) from Vandenberg Air Force Base in California.

At 7:17 a.m. PDT (14:17 UTC), the Falcon 9 launched, which was the first of three RADARSAT satellites deployed about 54 minutes following launch.

After stage separation, the Falcon 9 returned to SpaceX’s Landing Zone 4 at the Air Force Base. The first stage for the RADARSAT Constellation mission previously supported Crew Dragon’s first demo mission in March 2019.

The RADARSAT Constellation Mission shows Canada’s excellence in Earth observation from Space. The RADARSAT Constellation Mission is made of three identical C-band Synthetic Aperture Radar (SAR) Earth observation satellites built by MDA, a Maxar Company.

The RADARSAT Constellation Mission will scan and collect daily revisits of Canada’s vast territory and maritime approaches, like the Arctic, up to four times per day. The three-satellite configuration can also access any point of 90% of the world’s surface.

The RADARSAT Constellation Mission supports the Government of Canada to deliver responsive and cost-effective services for fields like maritime surveillance, ecosystem and climate change observation.

For example, the RADARSAT Constellation Mission will:

  • Help create precise sea ice maps of Canada’s oceans and the Great Lakes to facilitate navigation and commercial maritime transportation. Each satellite also carries an Automatic Identification System receiver, allowing improved detection and tracking of vessels of interest.
  • Collect highly-accurate data that will let farmers maximize crop yields, while reducing energy consumption and use of potential pollutants.
  • Take and provide images of areas affected by disaster to help organize emergency response efforts and protect local population.

Hercules SLR is one of many proud Canadian suppliers to supply rigging equipment, hardware and safety training to make the RADARSAT Constellation Mission possible.

Crosby Guest Blog: Shackle Inspection & Care

crosby shackles

CROSBY SHACKLES 

Crosby shackles are a popular option for lifting applications. Time-tested and work proven, Crosby has made their mark in rigging—they’ve produced the first wire rope clip, quench and temper fittings (this makes performance more reliable) and were the first to fatigue-rate products. Their shackles are particularly popular – read on to learn more about Crosby shackles and how to use them safely, a handy interactive inspection checklist and more tips for best use. 

CROSBY SHACKLES: 3 MAIN SHACKLE TYPES

Round pin shackles can be used for lifting applications and others like tie down, towing or suspension applications when the load’s strictly applied in-line.

Screw pin shackles are used for pick and place applications. Pick and place applications are when a load is moved to its desired location, and the screw pin is tightened before each pick.

Bolt-type shackles can be used in any applications that round pin or screw pin shackles are used. They’re also great for long-term or permanent installations where the load may slide on the pin, which causes it to rotate. The other way to secure a shackle includes using a nut and cotter, which eliminates the need for you to tighten the pin before each lift or movement. 

CROSBY SHACKLES: USE THEM SAFELY  

Before you put your Crosby shackle in service, make sure your shackle’s in good condition. To do so, look for these conditions:

  • The shackle’s pin works freely and fits correctly. 
  • The pins are undamaged, have no considerable wear and fit properly from the opposite side of the shackle. 
  • The load line and jaw opening are aligned.
  • The pin is always seated and is ‘matched’ to the body.
  • The shackle is the right material, size and type for the proposed lift.
  • Shackles are stored in a dry, cool place.

CROSBY SHACKLES: INSPECTION 

It’s important to inspect your rigging equipment frequently. Ideally, this happens before use, during (check for points of stress or tension during use) and after use. Inspection is important to prevent equipment failure, which can lead to damaging the load entirely, or worse—injure or kill workers’. 

Check your shackle before use. If any of these conditions are present, remove your shackle from service and have it inspected, repaired or replaced. 

  • The shackle’s jaws or pins are distorted.
  • The shackle isn’t stamped with is safe-working load (SWL).
  • The shackle is home-made (never use homemade shackles).
  • The shackle’s pin does not work freely, or fit correctly in the shackle’s opening. 
  • The pins’ threads are damaged, worn down or don’t easily screw in from the opposite side of the shackle. 
  • The unthreaded hole is enlarged – a hole too big places unnecessary strain on the loaded shackle. 
  • The shackle has wear that’s reduced its diameter by more than 8% of its original diameter. To test for cracks that may be hidden, tap them with a hammer. A shackle in good-condition should ‘ring’ clearly.
  • The shackle’s pin has been replaced, especially if it’s been replaced with anything but a pin. 

CROSBY SHACKLES: USE THEM SAFELY OR NOT AT ALL 

There are a few things to keep in mind when using shackles for securing and lifting applications. 

  • When you use shackles in conjunction with multi-leg slings, you must give consideration to the angle between the legs of the sling. 
  • As the angle increases, so does the load in the sling leg, and as a consequence, any shackle attached to the leg. 
  • Try to avoid erratic loading of the shackle – to do this, place a loose spacer on either end of the shackle’s pin, or use a shackle with a smaller jaw. 
  • If using a shackle to secure the top block of a rope block set, the load on the shackle is increased by the value of the hoisting effort. 
  • Take care to make sure the shackle and assembly above the hook is the right capacity. 
  • It’s important that on shackles fitted with a nut and bolt pin, the length of the bolt’s plain portion will cause the nut to jam on the inner end of the thread, and not on the shackle’s eye. This leaves the bolt free to rotate.
  • Be sure the bolt and nut are cross-drilled for the fitting of a split cotter pin.

Guest Blog: Crosby Talks Forged Wire Rope Clips VS. Malleable Cast Iron Clips

crosby wire rope clips at hercules slr

FORGED STEEL WIRE ROPE CLIPS VS. MALLEABLE CAST IRON CLIPS

What’s the difference between wire rope clips? Guest blogger Danny Bishop, Director of Training for Crosby stopped by Hercules SLR is here to share some information about the difference between malleable cast iron and forged U-Bolt clips.

Read on to discover his expert tips for rigging with U-Bolts. 

 

crosby rigging, hercules slr

 

 

 

 

 

 

 

U-Bolt style wire rope clips are one of the most commonly used accessories in the world of rigging. They can be found in many lifting and non-lifting applications.

Some common applications include winch lines, crane hoist lines, suspension cables, barrier cables, guy wires and many more applications. However, it is critical that the user know there are differences between a forged steel wire rope clip and a malleable cast iron clip.

The forged steel wire rope clip consists of a U-Bolt, two nuts and a forged steel base, which is sometimes called the saddle.

The malleable cast iron U-Bolt style wire rope clip consists of the same components as just mentioned except the clip base is NOT forged steel. In fact, it is a malleable cast iron, and that can make a big difference in the performance and reliability of the clip. The malleable cast iron base does not have the desirable material properties of steel, or the beneficial grain structure that a forged base provides. Although, malleable cast iron products have their place in industry, it is not the manufacturing process of choice for wire rope clip bases. This is especially true if the wire rope clip could be used in a critical application.

Notice that some standards do not allow the use of malleable cast iron clips in critical applications. One example would be ASME B30.5 which states that “Wire Rope Clips shall be drop-forged steel of single saddle (U-Bolt) or double saddle clip. Malleable cast iron clips shall not be used. “ASME B30.26 also states: “Saddles shall be forged steel.”

Additionally, shortcuts in the production process of the bases may also indicate there could be other shortcomings of the product. In some recent testing of malleable cast iron clips, it was found that U-Bolts fractured prior to achieving the recommended forged U-Bolt Clip torque, on 2/3 of the assemblies tested. (See picture of test mentioned).

Also consider:

  • Malleable Cast Iron Clip bases are significantly different from forged bases in size, shape and appearance. See figure 1 to compare a Crosby forged clip base and a Malleable Cast Iron clip, both for ½” wire rope. 
  • Malleable Cast Iron bases are inconsistent in strength, and can have hidden defects. 
  • Malleable Cast Iron clips should not be used for critical applications.

Important: Preventative Equipment Maintenance

Preventative Maintenance

Underestimating the importance of equipment maintenance could be taking a toll on your bottom line. The saying “if it ain’t broke, don’t fix it” is too often the way some view equipment maintenance. Why pay for service on your equipment if there’s nothing wrong with it? Believe it or not, there are several reasons. All equipment is an investment — one that requires time and money to keep in optimal shape.

BENEFITS OF MAINTENANCE

Preventative equipment maintenance is key to extending equipment life and ultimately saving you time and money. While your perception may be that paying for preventative maintenance is unnecessary spending, the reality is that without it, you’re often left with more expensive repairs. At Hercules SLR we believe in the importance of preventative maintenance, here are just some of the reasons why:

KEEP EQUIPMENT RUNNING EFFICIENTLY

When equipment runs efficiently, work get done on schedule, keeping that optimal condition is key to maintaining that level of equipment efficiency. If maintenance is overlooked, efficiency suffers and ultimately, your bottom line suffers as a result.

SMALL PROBLEMS BECOME BIGGER PROBLEMS OVER TIME

We’ve all seen it; something isn’t working exactly the way it used to, but it isn’t affecting the job, so we continue, sometimes even adjusting how we use the piece of equipment to keep things moving. While it may seem like this is the most efficient way to get the job done in the short term, it could cause you major problems long-term.

THE BIGGER THE PROBLEM, THE MORE THE EXPENSE

While it may seem like it makes no sense to spend the time and money to have your equipment inspected or repaired when you’re able to work around it, the reality is that waiting, is going to cost you even more. Bigger, more complex repairs come with a bigger price tag. Think of more than parts? yes, a more complex problem will likely come with having to replace more and/or larger parts that are expensive, but it doesn’t end there.

Larger problems often translate to more downtime, the more downtime means you’re suddenly behind schedule and/or unable to take on a new project. Employees scheduled to use that equipment need paying, so now you are paying for work that cannot be done during the downtime.

Don’t wait for the bigger problem — invest in the small one.

REDUCE INJURIES AND FATALITIES

Within the construction industry, 17% of fatal construction accidents are due to contact with objects and equipment. If your equipment isn’t being serviced on a regular basis, there’s a chance it isn’t working properly. If it isn’t working properly, you’re increasing your chances of workplace injury or death because of equipment failure.

Regardless of how much safety training you or your employees have been through, they don’t have control over equipment failure. Of course, there will always be unexpected breakdowns, but you can minimize them through being proactive about your equipment maintenance.

Workplace injuries and fatalities are tragic and expensive. Company morale suffers, and so does your bottom line. One of the benefits of maintenance doubles as a proactive step in reducing the number of injuries or fatalities you have on site. You can’t put a price on your team’s safety in the field.

 TRAIN OPERATORS AND TECHNICIANS

In conjunction with technology, there is no substitution for the human touch. It takes a trained operator to understand the problem and a trained technician to know how to fix it or to alert someone that it needs repairing. Educating your equipment operators and any technicians you have on staff is key to extending the life of your equipment, as they will be sure that small problems don’t turn in to big ones.

If training isn’t feasible, there needs to be a summary of best practices and an operation manual in place so you can ensure operators are using the equipment the way it was meant to be used. Always respect all weight limits and guidelines. An untrained equipment operator could unintentionally cause costly repairs, so make sure the best practices and expectations are outlined clearly and regularly.

SET AND STICK TO A MAINTENANCE SCHEDULE

Every piece of equipment is different. They all have their own intricacies and need a maintenance and repair schedule to match. Rather than waiting for parts to cause a problem, replace them when they are scheduled to be replaced.

How do you know when that is? The piece of equipment will have an original equipment manufacturer (OEM) maintenance recommendation. Commit to it. It may seem like by being proactive you’re attempting to fix something that isn’t broken, but trust us, neglecting to do this will result in expensive repairs.

CONDUCT REGULAR INSPECTIONS

No, inspections are not the same thing as maintenance schedules. equipment should be inspected every time it’s used. Trained operators should know what to look and listen for to ensure equipment is working properly. Checking for simple things, like signs of wear on equipment, can go a long way. The reality is equipment is often used with vibration, high temperatures and friction? all of which contribute to the wear and tear. Add age to the mix, and you have a recipe for deterioration.

This happens with all equipment, and the key to extending equipment life is to make sure you do something as simple as adding an operator visual inspection to your equipment use requirements. Noticing slight wear and tear may seem small, but these things can be identified through a visual inspection and fixed before they cause a larger problem.

HOW QUALIFIED ARE THE TECHNICIANS INSPECTING YOUR GEAR?

When it comes to inspections, testing, repairs and certification, you need to know that you and your equipment are in safe and experienced hands.

The Lifting Equipment Engineers Association (LEEA) is established across the globe as the leading representative body for all those involved in the lifting industry worldwide. They provide third party training and examination for technicians in the lifting equipment industry.

At Hercules our inspectors have undergone this internationally recognized training and some hold multiple diplomas.

OUR TECHNICIANS ARE:

  • Familiar with the most recent technology in the lifting industry
  • Skilled and confident in their inspection skills
  • Constantly learning and expanding their knowledge
  • LEEA Registered Technicians

Crosby Loves Hooks with Latches – Standards & Safety

Crane Operator Crushed Between Two Steel Frames When Rigging Failed

The operator of an overhead crane had been using a chain sling attached to the hook of the crane, and was setting it up into a single choker hitch to pick up and turn over the steel frame, that was lying horizontally on two sawhorses. The hook on the sling did not have a safety latch. The operator was standing between the load and another steel frame that was leaning vertically against the shop platform. The chain disconnected from the hook and the vertical steel frame fell towards him. He was crushed between the two steel frames. [Source: OSHA Case Histories – Rigging Accidents- Case History #7]

Possible ways to prevent this type of accident:

  • Ensure that workers do not place any part of their bodies into areas where they might become trapped when operating an overhead crane.
  • Ensure that the tools and equipment used are regularly inspected for defects and are replaced or repaired as needed.
  • Ensure that workers who use cranes are trained in rigging procedures.
  • Perform daily inspection of cranes using safety checklists to ensure that all equipment is working properly.
  • Ensure that the hook has a working safety latchand if not, is moused.

Invest in tomorrow by practicing safety today! There are several organizations that are dedicated to maintaining and progressing safety standards. ASME has sustained safety standards for the Crane, Rigging, and Lifting industry. One of the most frequently referenced standards is ASME’s B30 Safety Standard for Cableways, Cranes, Derricks, Hoists, Hooks, Jacks, and Slings.

ASME B30 is referenced throughout Crosby literature and training material. The many volumes cover a wide variety of topics, but there is a consistency to the guidance offered. For example, latches are discussed repeatedly appearing in B30.2 (Overhead Cranes), B30.5 (Mobile Cranes), B30.10 (Hooks), B30.23 (Personnel Lifting), and others.

When it comes to the use of latches, B30.16 (Overhead Hoists) summarizes it perfectly:
“Hooks shall be equipped with latches unless use of the latch creates a hazardous condition.”

Columbus McKinnon Corporation (NASDAQ: CMCO), a leading designer, manufacturer and marketer of motion control products, technologies and services for material handling, has expanded its portfolio of rigging attachments for synthetic slings to include CM Quick Connect HooksCM Flat Eye Rigging Hooks and a more comprehensive line of CM Weblok Assemblies.

“Columbus McKinnon is excited to offer a comprehensive line of American-made products to meet customer demand for safe and high-quality synthetic sling rigging attachments,” said Troy Raines, Global Chain and Rigging Product Engineering Manager. “We know customers are interested in protecting their investments and their people. We designed our rigging products to help them do just that, offering unique features that extend sling service life, while increasing operator safety and productivity.”

CM Quick Connect Hooks are a quick and easy way to add load attachment points to any synthetic sling by eliminating the need for additional hardware or assembly tools. Designed with a large, flat bearing surface and recessed area that together prevent the sling from bunching and shifting, Quick Connect Hooks allow synthetic slings to be used safely and at full capacity. In addition, to help ensure easy and proper rigging, Quick Connect Hooks are color coded to match common synthetic sling capacities.
