The Skylotec Claw Vertical Fall Arrest Sleeve is built to travel smoothly along a vertical system while providing fall arrest when needed. The Skylotec Claw is engineered to fit 3/8 Inch and 5/16 Inch solid core wire rope. This high-quality, lightweight stainless-steel device features redundant safety features to reduce your risk of improper installation. The Skylotec Claw Vertical Fall Arrest Sleeve also has a replaceable shock-absorbing pack and an anti-gravity locking system. Two hands are required to operate The Skylotec Claw to prevent the unintentional opening of the sleeve. The shackle and swivel carabiner allows you freedom of movement with maximum ease of use.
