Product Information

  • Allen 40mm Dynamic Double Swivel Block - A20402

    New for 2023. 40mm dynamic blocks are perfect for use on main, jib and spinnaker sheets on dinghies and keelboat control lines. 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

    Key Features We Love

  • 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 – The 40mm range features a large central hole, which can be used as a becket (tying-off point). Specific becket variations are also available.
