Patented, compact, lightweight device is a great alternative clunky snatch blocks. Can be used with a winch’s synthetic rope to increase pulling power and change direction. Used in conjunction with a soft shackle. Patented rubber fingers help retain the rope from exiting the pulley groves, preventing premature rope failure. Oversized hole radius provides a smooth surface, and keeps the soft shackle’s legs from rubbing on the ring’s edges. Friction surface is treated with Teflon for decreased friction and heat dissipation. For use with 3/16”–1/4” synthetic rope only. Made from billet-machined 6000-series aluminum with a Mil-A-8625 F hard-anodized surface. The rope retention pulley showcases a 12,000 lb. working load limit and weighs just 8.1 oz. Made in the U.S.A..
