The S-hook has a bigger clasp than the included standard hardware which makes it easier to attach for larger applications. The hardware hooks are rubber coated to protect your vehicle. 1.5” inch thick straps which extend from 9” in - 3' ft. The straps feature an S-hook fixed to one end of the strap and a zinc plated steel carabiner at the other. The hooks connect to the cargo net and a heavy-duty cam buckle in the center is used to cinch the strap tight. This kit is made to work with the cargo nets made by Gladiator Cargo Nets.
