Ronstan RF72100 Series 75 Ratchet Single

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
servicing or customisation.
