4” Cable Pulley
4-inch cable pulley stamped from two cold rolled steel plates and riveted with six evenly spaced rivets for structural integrity and balanced load distribution. The larger 4-inch diameter reduces cable bend angle and wear compared to 3-inch pulleys, making this size preferable for heavier doors or installations where cable longevity is a priority. The heat-treated inner ring resists groove wear across extended service life. Zinc plating protects against corrosion in the garage environment. Designed for the cable guide position on torsion-spring residential sectional door systems.
