Designed with rigors of tree work in mind, the Tech11 is an 11 mm rope constructed with an aramid sheath and nylon core. When used as a flip-line, it offers great abrasion resistance, incredible durability and security. This rope has been in development and field tested for several years. It has been exposed to some of the roughest conditions by rope access, fire rescue and arboriculture professions. Equipped with a double locking steel snap hook on one end and a sewn eye termination with a blue plastic thimble on the other end. Made in the U.S.A.
