A2040 - Allen 40mm Dynamic Block: Single
The Allen Dynamic range is generally the best choice for applications that require constant sheave movement.
Bearings – Dynamic Blocks feature Allen's 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's patented Ultra-Strap is used in their 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 – The 40mm range features a large central hole, which is designed to be used as becket (tying off point).
