Allen 2021HK Single 20 mm Dynamic Block with Hook.

A good hook and pulley for the Laser outhaul system. These blocks are standard on all boats upgraded with Allen parts and blocks.

Allen 20 mm Single Dynamic Blocks are for applications that require constant sheave movement.

Dynamic Blocks feature Allen Brothers 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.

The patented Ultra-Strap is unique when compared to other designs because of its coining process.

This process strengths the strap, making it more reliable and hard-wearing as well as making it much more rope friendly than other designs.
