20mm Articulating Double Dynamic Block.

This articulating double block is the only one of its kind available on the market. The blocks can articulate freely from one another allowing each to align perfectly with the rope angle.

This block offers low friction and fast rolling speeds. It’s lightweight and strong, making it ideal for dinghies, windsurfing, kitesurfing and anything else that runs smaller diameter lines. 

Allen Dynamic range is generally the best choice for applications that require constant sheave movement.

Bearings – Dynamic Blocks feature Allen 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.

Ultra-Strap – Allen patented Ultra-Strap is used in Allen 20, 30 & 40mm Dynamic blocks. The Ultra-Strap is unique when compared to other designs because of its coining process. This process strengthens the strap, making it more reliable and hard-wearing as well as making it much more rope friendly than other designs. The Ultra-Strap was the first marine industry block designed to work specifically with a rope attachment.

Becket – Allen 20 & 30mm blocks offer a large central rivet which not only reduces the overall weight but also offers a rope friendly attachment, perfect as a tie-off point when being used in a cascade system.
