1829 × 51 × 0.9mm Bright-Polished 304 Stainless Steel Piano Hinge

This light-duty stainless steel piano hinge, also known as a continuous hinge, measures 1829mm long and 51mm wide when fully open. It is manufactured from 0.9mm-thick Grade 304 stainless steel with a bright-polished finish.

Piano hinges were originally developed to hinge the long keyboard covers and lids fitted to pianos. They are now widely used in cabinet making, furniture, boxes, long lids and access panels where continuous support is required along an extended hinged edge.

The 51mm open width provides broader fixing leaves while retaining the lightweight 0.9mm construction. The in-line fixing holes are positioned at 101.6mm centres and countersunk for No.4 woodscrews. The hinge has a 3.3mm pin and 12.7mm-long knuckles.

Supplied as one complete 1829mm hinge length. It may be cut to a shorter required length using suitable stainless-steel cutting equipment.

Why choose a 51mm-wide light-duty hinge?

The 51mm open width provides broader leaves and more fixing area than narrower light-duty piano hinges. The 0.9mm leaf thickness retains a slim, lightweight profile for appropriately sized furniture, boxes, lids and panels.

Why use a continuous hinge?

A continuous hinge runs along the hinged edge instead of concentrating the fixing at several separate hinge positions. This can help distribute movement while maintaining alignment along a long lid, door or panel.

Cutting and installation

1. Confirm that the hinge dimensions suit the intended application.
2. Measure and mark any required cut carefully.
3. Use suitable stainless-steel cutting equipment and protective equipment.
4. Remove sharp edges and metal swarf after cutting.
5. Align the complete hinge before marking the fixing positions.
6. Select suitable No.4 woodscrews for the substrate.
7. Test movement and alignment before final tightening.

Fixing screws are not confirmed as included and must not be advertised as supplied.
