60MM BLOCK - SINGLE

A2060 - Allen 60mm Dynamic Single Block 

Heavy-Duty Sailing Block for Keelboats & Catamarans

The Allen 60mm Dynamic Single Block is engineered for the demands of keelboat and catamaran sailing, delivering smooth, reliable performance across a full range of rigging applications. From jib sheet systems to mainsheet controls and everything in between, this block is built to handle high loads with effortless efficiency — whether you're racing offshore or pushing hard on the inshore circuit.

Swivel Lock System

One of the standout features of this block is its integrated swivel lock, positioned at the head of the block. A simple turn of the locking screw gives you full control: lock the swivel in precise 90-degree orientations for fixed-lead applications, or unlock it completely for free-spinning versatility. This dual-mode functionality makes the Allen 60mm Dynamic Single Block one of the most adaptable blocks on the market, responding instantly to the changing demands of competitive sailing.

Patented Bearing System

At the core of this block lies Allen's industry-leading twin-row stainless-steel ball bearing system, running on a stainless-steel rail. This patented design delivers exceptional load-carrying capacity and outstanding long-term durability, outperforming conventional bearing systems that rely on plastic rails — a critical advantage when sailing in demanding conditions with high sheet loads.

Becket Attachment

The large central hole becket provides a lightweight, rope-friendly attachment point, reducing the overall weight of the block while offering a secure and reliable tie-off point. Perfectly suited for cascade systems, purchase arrangements and multi-purchase tackles, the becket ensures clean, friction-free rope management in even the most complex rigging setups.

Built for performance, designed for versatility — the Allen 60mm Dynamic Single Block is the go-to choice for keelboat and catamaran sailors who demand the very best from their deck hardware.
