A2040SC - 40mm Dynamic Block with Shackle Swivel
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.
Swivel Head - Featuring a 360-degree swivel head with a 4mm shackle. The shackle is load rated higher than the block so, although it might look small, it is plenty strong enough.
Becket – The 40mm range features a large central hole, which is designed to be used as becket (tying off point).
