Allen Brothers 40mm Dynamic Block with Swivel Head High Load
Allen Brothers 40mm Dynamic Block with Swivel Head High Load
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.
