1829 × 38 × 1.2mm Grade 304 Stainless Steel Piano Hinge

This medium-duty stainless steel piano hinge, also known as a continuous hinge, measures 1829mm long and 38mm wide when fully open. It is manufactured from 1.2mm-thick Grade 304 stainless steel with a self-colour finish.

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

The 1.2mm leaf is the lightest option within this medium-duty hinge group. It provides greater firmness and rigidity than lighter-duty continuous hinges while retaining a relatively slim profile.

The fixing holes are positioned in line on the opposing leaves at 101.6mm centres and countersunk for No.6 woodscrews. The hinge has a 3.3mm-diameter pin and 25.4mm knuckle length.

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

Why use a continuous hinge?

A continuous hinge supports the hinged edge along its length rather than concentrating movement at several separate hinge positions. This can help maintain alignment and distribute movement across a long lid, door or panel.

Cutting and installation

1. Measure and mark the required finished length.
2. Use suitable stainless-steel cutting equipment and appropriate protective equipment.
3. Remove sharp edges and metal swarf after cutting.
4. Align the complete hinge before marking the fixing positions.
5. Select No.6 woodscrews of a suitable length and material for the substrate.
6. Test alignment and movement before final tightening.

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