Allen Brothers 30mm Dynamic Cheek Block (A2036)
The Allen Brothers A2036 is a 30mm single Dynamic cheek block, designed for deck-mounted line management where efficient alignment and low-friction performance are essential. With a maximum rope diameter of 8mm, it is ideal for guiding control lines along decks, into cleats, or around corners.
Built on Allen’s proven Dynamic platform, it is optimised for systems requiring constant sheave movement.
Profix Cheek Adapter for Articulating Alignment
The A2036 is mounted on Allen’s Profix cheek adapter, allowing the block to articulate under load.
This provides:
- Up-and-down movement to align with the rope angle
- Reduced side-loading and improved efficiency
- Smooth line deflection across changing lead angles
The block is secured via a single fixing point through the head of the Profix adapter, making installation simple and effective.
Ideal for Deck Line Management
The cheek block format makes the A2036 particularly suited to:
- Leading lines along the deck
- Deflecting lines into cleats
- Guiding control lines around corners or obstacles
Its articulating design ensures consistent performance even where line angles vary.
Dynamic Bearing System for Low-Friction Performance
At the core of the A2036 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 handling and long-term durability.
A Practical Solution for Deck-Mounted Systems
The A2036 combines the reliability of the Dynamic bearing system with the flexibility of an articulating cheek block design.
For sailors looking to manage control lines cleanly and efficiently on deck, it offers a durable and well-aligned solution within the Allen 30mm Dynamic range.
