Each hinge measures 3.5 inches by 0.625 inches radius and is constructed from heavy-gauge cold-rolled steel for structural durability. The satin brass finish delivers a clean, polished look suited to standard interior door applications. The 5-knuckle design provides smooth pivot action and a finished appearance, while countersunk screw holes allow fasteners to sit flush with the hinge leaf for a professional result.

These hinges are appropriate for standard interior door installations in residential and light commercial settings.
