Barton Marine Size 2 Single Upright Block

The Barton Marine Size 2 Single Upright Block is an essential rigging component for sailors and boaters who demand reliability in their running rigging systems. Built for both cruising and performance applications, this single upright block serves as a directional control point in mainsheet, jib sheet, and outhaul systems where space is limited and efficiency matters. Whether you're managing lines on a cruiser, racing a keelboat, or optimizing tackle on a commercial vessel, a properly sized block system is the backbone of smooth, responsive sail handling.

This single upright block features Barton Marine's proven block design, engineered to reduce friction and distribute load efficiently across your rigging system. The compact upright configuration allows you to mount it in tight locations—on booms, masts, or deck hardware—without sacrificing mechanical advantage or durability. Its lightweight profile at just 0.2 pounds makes it ideal for minimizing topside weight, a critical consideration on performance-oriented vessels. The precision engineering ensures smooth line movement under load, reducing fatigue on both rope and hardware during extended sailing sessions.

Experienced boat owners and riggers consistently choose Barton Marine blocks for retrofit projects and new builds alike. The Size 2 single upright works seamlessly with standard rope diameters and integrates with existing Barton Marine block systems and universal shackle connections. Installation is straightforward—secure the upright fitting to your boom, mast track, or rail system using appropriate hardware for your vessel type. Whether you're upgrading aging rigging, fine-tuning a performance cruiser, or maintaining a well-used passage-maker, this block delivers the reliability and ease of operation you need when it matters most on the water.
