Continuous Piano Hinges

Continuous piano hinges are long, narrow hinges that run the full height of a door, lid, or panel, distributing load evenly and supporting smoother movement. Originally used on piano lids, these hinges are now installed on cabinets, fold-down benches, tool chests, and doors where continuous support matters. Unlike standard butt hinges that support a door at two or three fixed points, a continuous hinge spans the full length of the panel, reducing stress concentration and keeping doors and lids properly aligned over time — even under heavy or frequent use. Most piano hinges can be cut to a custom length using a hacksaw or metal cutoff wheel, making them adaptable to a wide range of project sizes.

Buying Guide

1. Material & Environment: Choose aluminum for lightweight, corrosion resistance; stainless steel for moisture-prone or high-use areas; and steel for general strength and economy. For marine or outdoor use, see our stainless steel hinges.
2. Length & Coverage: Match the hinge length to the full height of the door, lid, or panel for even load distribution and to prevent sagging or misalignment. Piano hinges are easily cut to a shorter length when a custom size is needed.
3. Load & Usage: Continuous piano hinges are well-suited for frequent use and heavy loads because they support the entire length of the opening rather than just at discrete hinge points.
4. Duty Level & Series Selection: Continuous piano hinges are grouped by series to reflect material thickness, load capacity, and intended use. Lighter-duty series work well for cabinets and furniture hinges, while heavier-duty series are designed for doors, benches, and high-use or industrial applications.
5. Mounting Style: Confirm whether you want surface-mount models with pre-drilled holes or non-drilled versions for welding or custom installations. For weld-on applications, also see our weld-on hinges.
6. Finish & Aesthetics: Select a finish that complements your project and resists wear. Use shiny metals for decorative furniture pieces, or utilitarian finishes for industrial or cabinetry applications.
