Ronstan 55mm Ratchet Cheek Block RF56151A

Ronstan Ratchet Orbit Cheek Blocks™ are available in both Left and Right handed and are either screwed or bolted to surfaces.

The unique sheave design has 12 gripping faces which directly resist loaded line movement. Traditional designes have only 8 faces with an angled resistance to line movement. Our Generation 2 design has straight resistance faces which both distribute the load and minimise rope wear. These faces are offset from the radial line, to draw the rope down into the gripping area when under load.
