Barton Marine Size 2 Single Cheek Block

The Barton Marine Size 2 Single Cheek Block is a precision-engineered pulley system designed for sailors and boaters who demand reliability in demanding marine environments. Whether you're racing keelboats, cruising coastal waters, or managing complex rigging systems, this single cheek block serves as a critical component in mainsheet travelers, boom vang systems, and control line routing. Built by Barton Marine—a trusted name among performance sailors worldwide—this block combines traditional craftsmanship with modern materials to deliver the smooth, quiet operation you need when seconds and consistency matter on the water.

At the heart of this block lies a precision-molded acetal sheave mounted on a large-diameter brass bearing, a design philosophy proven across thousands of offshore racing campaigns and commercial marine applications. The plain bearing construction—absent ball or roller elements—ensures virtually frictionless operation under the sustained, high-load conditions typical of sail control systems. The single cheek configuration allows the block to function as both a directional change and a load-bearing component, while the 0.25 lb weight keeps parasitic mass minimal, critical for efficiency in performance sailing. The compact 2 × 1 × 5-inch footprint makes it suitable for confined deck spaces, transom installations, and retrofit applications where room is limited but strength cannot be compromised.

This block is ideal for racing sailors, cruising enthusiasts, and boaters running modern control systems who need predictable load distribution and long service life. It integrates seamlessly into existing Barton rigging networks and pairs well with standard marine rope and webbing in diameters compatible with Size 2 block openings. Installation is straightforward using deck hardware or boom tangs via the built-in mounting provisions. For anyone serious about maintaining peak rig performance and silent, efficient sail handling—from dinghy racing to cruising yachts—the Barton Marine Size 2 Single Cheek Block delivers the engineering and durability that separates premium equipment from the rest.
