A2040B - Allen 40mm Dynamic Block with Removable Bolt Block.
The Allen Dynamic range is generally the best choice for applications that require constant sheave movement.
The Ultra Strap on this block is held in place with a bolt and nut; allowing it to be easily removed for quick and easy fitting.
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).
