20mm Single Dynamic Cheek Block.

This block is mounted to our Profix cheek adapter which allows for articulation, so the block can lift up and down to align correctly with the rope. Ideal for leading lines along a deck, into a cleat or around corners. Held in place by one screw through the head of the Profix cheek adaptor.



Bearings – Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail. Our Dynamic range is generally the best choice for applications that require constant sheave movement.
