Allen Brothers 30mm Dynamic Composite Cheek Block (A2036M)
The Allen Brothers A2036M is a 30mm single Dynamic composite cheek block, designed for fixed mounting where clean, low-friction line management is required. With a maximum rope diameter of 8mm, it is ideal for guiding control lines along decks, into cleats, or around corners on dinghies and performance boats.
As part of the Dynamic range, it is optimised for systems requiring constant sheave movement and reliable long-term performance.
Fixed Composite Cheek Design for Secure Mounting
The A2036M is designed to be mounted directly onto a flat surface, providing a stable and secure solution for line deflection.
This offers:
- Solid, low-profile installation
- Reliable performance in fixed positions
- Clean routing of control lines across the deck
The block is secured using two fixing points:
- One through the centre of the sheave
- One through the countersunk hole in the head of the block
This ensures a strong and stable connection, even under load.
Ideal for Deck Line Management
The cheek block format makes the A2036M particularly suited to:
- Leading lines along the deck
- Deflecting lines into cleats
- Guiding ropes around corners or fittings
Its fixed design ensures consistent alignment in applications where the lead angle remains relatively constant.
Dynamic Bearing System for Low-Friction Performance
At the core of the A2036M is Allen’s patented Dynamic bearing system:
- Twin rows of stainless steel ball bearings
- Stainless steel bearing rail
- Acetal sheave
This configuration delivers smooth, low-friction operation, even under continuous adjustment. Compared to systems using plastic bearing races, the stainless-steel rail improves load distribution and long-term durability.
A Simple and Durable Deck-Mounted Solution
The A2036M combines the proven performance of the Dynamic bearing system with a robust, fixed composite cheek design.
For sailors looking for a dependable, low-friction solution for guiding control lines across the deck, it offers a clean, durable and effective option within the Allen 30mm Dynamic range.
