Schaefer Twin Sheet Block f/1-1/4" T-Track - Black

The Schaefer Twin Sheet Block for 1-1/4" T-Track in black is a hardcoat anodized aluminum rigging block engineered for sailboat deck hardware systems. This twin sheet block mounts directly to standard 1-1/4" x 3/16" T-track systems and delivers the low-friction, high-strength performance required for mainsail and jib control lines on cruising and racing sailboats up to 38 feet in length and 18,000 lbs displacement.

The block features an aluminum sheave that runs on Nomex/Teflon bearings, minimizing friction while handling high loads typical of sail trim applications. The articulating sheave design allows proper lead angles for multiple line paths, critical when routing control lines across the deck. A pin stop mechanism simplifies sheave adjustment, reducing downtime during rigging setup or maintenance. The hardcoat anodized aluminum construction resists corrosion from salt air and UV exposure, essential for extended cruising in coastal and offshore environments.

This block suits weekend cruisers seeking reliable, maintenance-friendly deck hardware and serious offshore sailors who demand proven rigging components. The 1-1/4" T-track compatibility integrates seamlessly with modern modular deck systems, allowing crews to reposition or add blocks without modification. The dual-sheave configuration handles paired control lines efficiently, reducing the number of separate blocks needed on deck and simplifying line management during active sail changes.

Schaefer Marine's T-track and block systems are standard equipment on production sailboats and custom builds worldwide. The twin sheet design represents the middle ground between single blocks and larger quad-sheave systems, offering flexibility for boats transitioning between cruising and performance sailing setups.
