ARB Snatch Block 20,000Lbs Ultra LightARB snatch blocks feature side plates that sit snug against the pulley, eliminating the possibility of the winch cable becoming trapped between the pulley and the side plates. The groove on the pulley itself tapers down to the center allowing for a variety of cable sizes (1 4" 1 2") to be used and ensures the cable is seated securely in the pulley, minimizing lateral movement. Features: Works with steel or synthetic winch lines Light weight design
