WIRE ROPE CONSTRUCTIONS -

When a center wire is replaced by a strand, it is considered as a single wire, and the rope classification remains unchanged.
There are, of course, many other types of wire rope, which are useful for specific applications.
Consult your Hercules SLR representative for further information on any other wire rope constructions.
