Allen 40mm Dynamic Single Swivel Block with High Load Sheave

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.

High Load Sheave – High load blocks feature a stainless-steel sheave. This upgrade offers even faster rolling speeds and lower friction when compared to the standard acetal sheave. The stainless-steel sheave allows the block to be paired with both rope and wire.

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.

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, it’s 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.
