40MM TRIPLE BLOCK

40mm Dynamic Tiple Swivel Block with Becket | New 2023 | High-Performance Block for Keelboats & Dinghies

New for 2023, the 40mm Dynamic Single Swivel Block with Becket is built from high-strength, lightweight glass-loaded nylon and combines Allen's renowned dynamic bearing technology to deliver a high-performance block perfectly suited for keelboats and dinghies.

Ideal for use on main, jib and spinnaker sheets on dinghies, as well as keelboat control lines, this block is the perfect all-round solution for building efficient purchase systems on board.

Patented Bearing System – Dynamic Block Technology Dynamic Blocks feature an exclusive patented bearing system using twin rows of stainless-steel ball bearings running on a stainless-steel rail. The ball bearings are caged for further friction reduction, delivering superior load-carrying capacity and outstanding longevity compared to conventional bearing systems on the market.

Swivel Head – 360° Rotation with Rated 4mm Shackle The block features a 360-degree swivel head fitted with a 4mm shackle that is load rated higher than the block itself — compact but more than strong enough for demanding conditions.

Becket – Build Efficient Purchase Systems with Ease This block features a dedicated becket moulding designed to allow easy construction of purchase systems. Ideal for mainsheet, cunningham, outhaul and vang controls, the becket provides a reliable and rope-friendly tie-off point for optimised sail trim.
