Allen 40mm Single Block

£37.28

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.
Ultra-Strap – the patented Ultra-Strap is used in Allen's 20, 30 & 40mm Dynamic blocks. The Ultra-Strap is unique when compared to other designs because of its coining process. This process strengthens the strap, making it more reliable and hard-wearing as well as making it rope friendly. The Ultra-Strap block is a great choice for dinghy jib or mainsheet systems.
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.

Maximum Working Load = 240kg. If exceeded the block may not perform as designed.
Breaking Load = 700kg. The load at which a major block failure is likely to occur.
