A2040LZ - Allen 40mm Dynamic Block: Single with Lacing Eye.
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.
Stand-Up - This block is assembled around a lacing eye and uses a spring to hold it upright. Ideal for spinnaker halyard blocks which are deck mounted or any other control line where the block needs to stand up.
Becket – The 40mm range features a large central hole, which is designed to be used as becket (tying off point).
