Pro-Ratchet 40 Block - Triple, Becket, Cleat

Pro-Ratchet 40 Triple Block with Becket and Cleat

Made from high-strength, lightweight glass-loaded nylon and featuring Allen’s Dynamic Bearing Technology, this high-performance block is suitable for both keelboats and dinghies.

This 40mm triple block is an excellent choice for catamaran mainsheet systems 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, providing superior load-carrying capability and longevity compared to other bearing systems.

Swivel Head

Features a 360-degree swivel head with a 5mm shackle. The shackle is rated higher than the block itself, so despite its compact size, it is more than strong enough for the application.

Swivel Lock

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

Ratchet

Features the sheave and mechanism from the Pro-Ratchet 40 for enhanced line-holding power. This ratchet is not switchable and is always engaged.

Adjustable Cam Cleat

The angle of the cam cleat arm can be adjusted easily by undoing the plastic plates on either side of the block.

Cam Cleat

This block comes fitted with the small A..77 cam cleat.

Becket

This version features a strong becket, designed for tying a rope around or attaching additional hardware.
