1834 × 51 × 1.2mm Polished Brass Continuous Hinge

This polished brass continuous hinge, also known as a piano hinge, measures 1834mm long and 51mm wide when fully open. Its 1.2mm-thick brass leaves provide continuous support along an extended hinged edge.

The broad 51mm open width and 1.2mm leaf provide a firmer construction and wider fixing surface than the narrower 38 × 0.9mm version. The polished brass finish gives the hinge a warm decorative appearance suited to furniture, display joinery, cabinets, long lids and other interior applications where it may remain visible.

This light/medium-duty hinge has 36 factory-produced countersunk fixing holes. Use suitable 2.5mm-diameter countersunk screws selected for the substrate and application. Screws must be ordered separately.

The hinge has a 6mm closed projection or depth. This measurement must not be presented as the leaf thickness, which is 1.2mm.

Supplied as one complete 1834mm hinge. It may be professionally cut to a shorter length using equipment suitable for brass. Regular lubrication is required to support smooth operation.

Why use a 51mm continuous hinge?

A continuous hinge supports the hinged edge along its length instead of concentrating movement at separate hinge positions. The 51mm open width provides broader fixing leaves than the 38mm version, which may be useful where a wider fixing surface is required.

Cutting, installation and care

1. Confirm that the dimensions and duty level suit the application.
2. Measure and mark any required finished length.
3. Use suitable brass-cutting equipment and appropriate protective equipment.
4. Remove sharp edges and metal swarf after cutting.
5. Align the complete hinge before marking the fixing positions.
6. Use suitable 2.5mm-diameter countersunk screws for the substrate.
7. Test movement and alignment before final tightening.
8. Lubricate the hinge regularly with a suitable product.

Fixing screws are ordered separately and must not be advertised as included.
