40mm Dynamic Single Swivel Hook Block.

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.

Swivel Hook Head – Featuring a 360-degree swivelling hook for super easy attachment. Ideal for lightweight control systems where removal needs to be quick.

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.
