CLGR® Block Sheave Stainless Steel Single Sheave is a durable and flexible rigging component built for smooth line handling and efficient power transmission in demanding maritime environments.
Made from AISI 316 stainless steel, it stands up to prolonged saltwater exposure, moisture, and harsh weather without rusting or losing strength. The articulated design allows the sheave to move and adjust as angles shift during operation—reducing stress on ropes and extending service life. This makes it especially useful on sailboats, mooring systems, and lifting gear where loads are constantly changing.
The single sheave runs with low friction and distributes forces evenly across the rope, improving performance while minimizing wear. Whether used in rigging, hoisting, or general rope handling, it offers the strength and flexibility you need for reliable day‑to‑day operation.
Available in multiple sheave sizes to suit different rope diameters. Custom options on request—just let us know your requirements.
