40mm Dynamic & 30mm Dynamic Linked Single Blocks.

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.

Linked A great choice for mainsheet systems which require a traveller block (30mm) and a mainsheet block (40mm) attached as closely together as possible. Linking the blocks results in a limited chance of snagging or failure. The linked blocks can also be used in spinnaker and pole launcher systems.

Becket The 40mm range features a large central hole, which can be used as a becket (tying-off point).
