63mm Cranked Steel Backflap Hinges – Bright Zinc Plated

These 63mm cranked backflap hinges provide a practical surface-mounted fixing for gates, shed doors and larger timber joinery. The cranked profile offsets the hinge leaves, helping adjoining surfaces sit in the required position when a standard flat backflap hinge would not provide suitable alignment.

Manufactured from steel with a bright zinc plated finish, the hinges have a protective zinc-coated surface suitable for general joinery applications. Each hinge measures 156 x 63mm when open and 84 x 63mm when closed. This listing contains one pair of hinges.

Product Specifications

Why Choose a Cranked Backflap Hinge?

The offset formed by the cranked leaves changes the position of adjoining components compared with a standard flat hinge. This can help achieve the required alignment on gates, doors and lids. The broad leaves mount directly onto the surface, avoiding the need to cut a traditional hinge recess.

Installation Guidance

1. Check that the cranked profile provides the required offset.
2. Position the hinges and mark the fixing-hole locations accurately.
3. Drill suitable pilot holes and secure using appropriate screws.
4. Check alignment and free movement before fully tightening every fixing.

Fixing screws are not stated as included. Select screws suitable for the substrate, fixing-hole size and intended environment.
