Allen 40mm Triple Block with Becket, Ratchet and Adjustable Cam Cleat.

Made from high-strength, lightweight glass-loaded nylon and featuring Allens dynamic bearing technology for a high-performance block suitable for keelboats and dinghies.

This 40mm triple block is a great choice for catamaran mainsheets or keelboat backstay systems.

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 5mm shackle. The shackle is load rated higher than the block, so although it might look small, it's plenty strong enough!

Swivel Lock: This block comes with a swivel lock moulding. The moulding allows the shackle to be locked in 90-degree orientations. It can be removed by undoing the shackle and removing it from the swivel pin.

Ratchet: Featuring the sheave and mechanism from the Pro-Ratchet 40 for additional line-holding power. This ratchet is not switchable so it is always on.

Adjustable Cam Cleat: The angle of the cam cleat arm can be adjusted by simply undoing the plastic plates on either side of the block.

Cam Cleat: This block comes with the small A..77 cam cleat.

Becket: This block version features a strong becket, designed to tie a rope around or attach another piece of hardware to.
