Rope ratchet is made super tough to take all the hard work you do. The outer casings are made from #6 - 33 percent glass filled nylon with interior mechanisms of die cast zinc. The rope is solid braided polyester or polypropylene and the hooks are zinc plated steel. With the 1/4" rope ratchet you simply attach the two hooks and pull the loose end of the rope for a secure, tight hold. Rope ratchets stay tight, locking in place as you pull the free end. To loosen you just pull the rope to reduce tension and push the handy thumb release. It's that easy. This rope ratchet holds ups to 150 lbs per ratchet. 8-Feet solid braided polypropylene rope. Actual body size: 2-1/4' x 1-1/4".
