Schaefer Clear Step Lead Block f/1" Stanchions

The Schaefer Clear Step Lead Block f/1" Stanchions is a precision marine hardware component designed for sailors and tactical watercraft operators who demand clean, efficient control line routing. This lead block solves a critical problem in deck layout: guiding furling control lines outside stanchion arrays to create a straight, unobstructed path aft to the cockpit. Whether you're managing sail systems on a cruising vessel or operating a specialized marine platform, this block eliminates chafe points, reduces friction-induced wear, and maintains sight lines across the deck.

Built from marine-grade stainless steel cheeks paired with a Delrin ball-bearing sheave, the Schaefer Clear Step delivers low-friction line travel and high load strength in a compact 3 × 1 × 5 inch footprint weighing just 0.3 pounds. The ball-bearing sheave design minimizes drag on control lines under load, while the stainless construction resists saltwater corrosion—critical for long-term reliability in harsh maritime environments. The block secures to 1-inch stanchions via a locking set mechanism, ensuring it remains fixed during dynamic sailing conditions or tactical operations.

This lead block is ideal for blue-water cruisers, racing sailboat crews, and marine professionals who operate vessels with standard 1-inch stanchion systems. Installation is straightforward: clamp the block onto the stanchion rail, position it to guide your control line outside the stanchion array, and lock it securely with the set screw. The clear design of the Delrin sheave allows visual inspection of line wear and condition, supporting preventive maintenance schedules. Compatible with standard marine furling systems and synthetic control lines, this block is a drop-in upgrade for any vessel seeking improved deck efficiency and operational safety.
