Allen 40mm Single Block with Swivel Head Fiddle & Cleat

40mm Single Block with Swivel Head Fiddle & Cleat

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 Allen's 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!

Fiddle – The fiddle sheave is a 20mm dynamic bearing sheave. This ensures that any purchase systems run as smoothly as possible.

Cam Cleat – The AL-0077, small aluminium cam cleat, is mounted to an adjustable stainless steel arm. The arm can be adjusted to suit your sheeting angle by simply loosening the nut and bolt through the centre of the block, loosening the side plates and retightening everything at the required angle.
