FACTOR 55 Rope Retention Pulley

The world’s first winch friction pulley with patented rope retention feature. A lightweight alternative to traditional heavy snatch blocks/pulleys. The RRP can be used to increase pulling power or redirect the winch line. The RRP is for use with SYNTHETIC ROPE ONLY and is to be used in conjunction with a soft shackle. During momentary slack, patented rope retention rubber fingers prevent synthetic winch rope from escaping the pulley groove preventing premature rope failure. The oversized hole radius provides a smooth rubbing surface and keeps the legs of the soft shackle from rubbing on the edges of the RRP. The critical friction surface has also been TEFLON treated to increase slickness and heat dissipation.

NOTE: Factor 55 Rope Retention Pulleys offer an alternative to traditional snatch block pulleys, though with some considerations for efficiency. It is important to note that these pulleys experience frictional losses, which can average between 10-20% depending on the load applied. Despite this efficiency reduction due to friction, Rope Retention Pulleys still provide mechanical advantage. Additionally, they offer practical benefits, including reduced risk of injury from pinched fingers, retaining the rope in the pulley ring under slack conditions(Patented Feature), elimination of the need to carry heavy snatch blocks, and faster rigging setups. When used appropriately, these pulleys are a reliable choice for recovery operations.
