Allen 40mm Single Block With Ultra-Strap
Allen 40mm Dynamic Single Ultra-Strap Block.
Made from high-strength, lightweight glass-loaded nylon and featuring Allens 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‚ Our patented Ultra-Strap is used in our 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.
Please Note‚ The picture used is of the A20401SR, removable ultra-strap block. This version, the A20401S, does not have a removable strap an is riveted through the centre rather than bolted.
