The SS4501 is a stainless steel door hinge 4.5x4.5 designed for smooth, long-lasting performance on commercial wood or metal doors. It features square corners and two ball bearings that reduce friction, allowing the door to swing more quietly and with less wear over time.
Built from corrosion-resistant stainless steel, the SS4501 is suitable for high-traffic environments such as offices, schools, apartment buildings, and commercial facilities. The hinge uses a removable stainless steel pin for easy installation and maintenance and fits standard 4.5″ × 4.5″ commercial hinge templates. Includes both wood and machine Phillips flat-head screws.
