Continuous Piano Hinges

About

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.
