Q. How about wire rope (steel cable)? A. For smaller structures, 3/16-inch wire rope might be fine; for larger structures, at least 1/4-inch. Note the working strength printed on the spool. Wire rope clips should be used in sets of three for loops and splices. Thimbles reduce stress on the wire rope, and allow easier attachment to a structure using a quick-link or shackle. Never saddle a dead horse -- place the saddle part of the wire rope clips on the live part of the line.
