10mm Dynamic Single Swivel Block with Becket
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 Head – Featuring a 360-degree swivel head with a 4mm shackle. The shackle is load rated higher than the block, so although it might look small, it’s plenty strong enough! Becket – This block has a specific becket (tying) moulding. The becket allows you to make a purchase system. Ideal for mainsheet, cunningham, outhaul, and vang controls.
