Allen 40mm Single Stand Up Block

40mm Single Stand Up 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 Allen's 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.

Stand Up – This block is assembled around a lacing eye and uses a spring to hold it upright. Ideal for spinnaker halyard blocks which are deck mounted or any other control line where the block needs to stand up.
