The SS4405 is a stainless steel door hinge 4x4 with two ball bearings for smoother, quieter door operation and long-term durability. Built for commercial and residential use, this hinge features square corners, a heavy-duty 5-knuckle design, and a removable stainless steel pin for easy installation.

Ball-bearing hinges greatly reduce friction and wear, making them ideal for high-traffic environments such as schools, offices, and apartments. The SS4405 fits standard commercial hinge templates and includes both wood and machine Phillips flat-head screws.
