Allen 20mm Single Cheek Block High Load

Allen 20mm Single Dynamic Cheek Block With High Load Sheave.

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.

High Load Sheave: By utilising a stainless-steel sheave with a slight V shape profile offers the ability to be paired with both wire and Dyneema. This design also reduces the deformation of the sheave under high static loads. These combinations result in less friction, higher working loads, better performance, and durability over the acetal sheave range.
