A20401BF-77 – 40mm Dynamic Single Swivel Block with Becket, Fiddle & Cam Cleat | High-Performance Block for Keelboats & Dinghies
The A20401BF-77 40mm Dynamic Single Swivel Block with Becket, Fiddle and Cam Cleat 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 brings together a dedicated becket, a 20mm fiddle sheave and an integrated adjustable cam cleat for the ultimate all-in-one deck solution.
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 for easy construction of purchase systems. Ideal for cunningham, outhaul and vang controls, providing a reliable and rope-friendly tie-off point for optimised sail trim.
Fiddle Sheave – Ultra-Smooth Purchase Systems The 20mm dynamic bearing fiddle sheave ensures that any purchase system runs as smoothly and efficiently as possible, even under load.
Adjustable Cam Cleat – Set Your Perfect Sheeting Angle The integrated A.77 small aluminium cam cleat is mounted on an adjustable stainless-steel arm. Simply loosen the nut and bolt through the centre of the block, loosen the side plates, and retighten everything at the required sheeting angle for a perfectly tailored setup
