40mm Dynamic Single Swivel Block.
Made from high-strength, lightweight glass-loaded nylon and featuring Allens 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 blocksfeature 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.
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, its plenty strong enough!
Becket The 40mm range features a large central hole, which can be used as a becket (tying-off point).Specific becket variations are also available.
