Sheave Straps for Extension Spring Garage Doors

These sheave straps are precision-formed, U-shaped steel components designed for use with extension spring garage doors. Each strap is pre-cut with mounting holes for easy installation on the sheave pulley assembly, allowing it to attach securely to wall brackets and act as a fixed pulley point.

Engineered to transfer the pulling force of the extension springs, sheave straps help ensure balanced and efficient lifting action when paired with compatible 3-inch or 4-inch sheave pulleys. Constructed from high-quality, durable metal, these straps deliver long-lasting reliability in demanding garage door environments.
