PRODUCT INFOFRMATION

Powerful grip
The patented extruded hole design, in conjunction with the groove profile of the sheave, provides a more powerful grip than conventional designs - up to 20:1 holding power. Unrivalled low weight is achieved by the use of a Torlon® ratchet pawl, high-grade machined alloy sheave and black Acetal hubs and bearings. ON-OFF switching knob is fitted to both sides of the swivel blocks (one can be removed if desired). Ratchet blocks can be disassembled for sheave replacement with RF72000.

Compositite C-Cleat™ and adustable cleat arm
The RF72175 Series 75 Ultimate Ratchet Block is fitted with our carbon reinforced C-Cleat™ for secure rope holding with low entry and exit efforts, and fairlead for fast action from any angle. Cleat arms are made of Grade 316 stainless steel and are adjustable for setting to your preferred cleating angle.
