A2030SC - Allen 30mm Dynamic Block: Swivel Block
The Allen Dynamic range is generally the best choice for applications that require constant sheave movement.
Swivel Head - the built in swivel pin allows this block to swivel once attached. Making it ideal for applications where the pulling forces may change direction (the swivel cannot be locked).
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.
Becket – Allen's 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.
