This rope grab is a solid performer that can be used as a ratchet or to grip a kernmantle rope whenever reliability and care are priorities. The compact, curved body is easy to grip and the secure, user friendly release mechanism makes putting this rope grab onto any rope - loaded or unloaded - a breeze. A specially designed cam protects your rope in the event of unexpected loading, but this unit is not designed as a belay or fall protection device. Made of anodized aluminum and will handle ropes up to 1/2" (13 mm). Weight 6.72 oz. (191g). Made in the U.S.A.
