A20401C – 40mm Dynamic Cheek Block | High-Performance Turning Block for Keelboats & Dinghies
The A20401C 40mm Dynamic Cheek Block 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, the A20401C is the perfect low-profile solution for flat surface mounting on any deck layout.
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.
Cheek Mount – Secure, Snag-Free & Self-Draining The A20401C is designed to be mounted flat to any surface using two fixing screws. Its domed head profile minimises the risk of lines snagging around the block, while two small drainage holes at the central fixing point ensure water can freely escape through the block — keeping it clean and reliable in all conditions
