Allen 40mm Single Stand Up Block
Allen 40mm Dynamic Single Stand Up 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.
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.
Becket‚ The 40mm range features a large central hole, which can be used as a becket (tying-off point).
