A ROPE’S BEST FRIEND Protect your ropes because your life or the lives of others depend on them. With Static Rope Edge Protection (STREP®), you can rest easy knowing that your ropes — regardless of application — will withstand any abrasive material the world throws your way. Constructed using the same proprietary nylon weave that is used in Chafe-Pro®’s Commercial Series, the STREP® system is designed to withstand sharp angles and abrasive surfaces and protect the static line contained within.
