Description
40mm Dynamic Single Stand Up Block.
New for 2023.
Made from high-strength, lightweight glass-loaded nylon and featuring Allen’s dynamic bearing technology for a high-performance block suitable for keelboats and dinghies.
40mm dynamic blocks are perfect for use on main, jib and spinnaker sheets on dinghies and keelboat control lines.
Bearings – Dynamic blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. The ball bearings are caged for further friction reduction. These features provide a superior load-carrying ability and longevity when compared to other bearing systems.
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 can be used as a becket (tying-off point).
