3-1/2 Inch Non-Mortise Hinge Pair

This pack contains two steel hinges with a polished brass finish. They are designed for surface mounting on bi-fold or similar doors. The non-mortise design allows installation without cutting recesses into the door or frame. Each hinge measures 3-1/2 inches.

Brass-Finish Steel for Light-Duty Doors

The steel construction provides adequate strength for standard interior bi-fold doors. The bright brass coating resists corrosion and matches traditional hardware. Surface mounting suits hollow-core or thin doors where mortising is impractical. Heavy entry doors or high-traffic openings may require a heavier grade hinge.

Questions about this item

Will these 3-1/2 In. non-mortise hinges line up with the screw holes on my existing bi-fold doors?

They are surface-mounted and designed for bi-fold doors, so the screw pattern matches standard non-mortise prep without requiring a mortise cut.

How can I confirm the polished brass finish is correctly applied after installation?

Inspect each hinge for a uniform bright brass colour across the steel leaves and verify the pin moves smoothly without binding when the door is opened and closed.
