The SS4404 is a stainless steel door hinge 4x4 with two ball bearings for smoother, quieter operation and long-term durability. Designed for commercial or residential doors, this hinge features 1/4″ radius corners, a heavy-duty 5-knuckle design, and a removable stainless steel pin for easy installation and maintenance.

Ball-bearing hinges are ideal for high-traffic environments because they reduce friction and wear, allowing doors to swing more smoothly over years of use. The SS4404 includes both wood and machine Phillips flat-head screws and fits standard commercial hinge templates.
