Description

The Allen A2023 20mm Double Dynamic Block with Becket is a compact, lightweight and durable double-sheave pulley designed to deliver smooth, low-friction performance in sailing and marine control-line systems. Part of Allen’s Dynamic range, this block is engineered for applications requiring frequent and continuous sheave movement.

Featuring Allen’s patented Dynamic Bearing System, with twin rows of stainless-steel ball bearings running on a stainless-steel rail, the A2023 provides efficient rope handling and reliable performance. Its stainless-steel Ultra-Strap construction adds strength and durability while remaining gentle on ropes.

The integrated becket provides a convenient tie-off point, making it easier to secure lines while helping to keep the load central through the block. Designed for smaller-diameter ropes, it is a practical choice for compact sailing control systems and pulley arrangements.
