Definition
Hinge — the mechanical fastening device that allows a door or window to swing. Engsel is made from steel (for structural doors) or brass (for visible, higher-grade applications) and is specified by load capacity and size. Standard door engsel are 2.5–4 inches, with heavy-duty sizes for commercial applications.
Example
An Indonesian wooden daun-pintu uses three 3-inch steel engsel mounted on the kusen frame — the engsel supporting the door's weight and allowing smooth operation, with quality directly affecting door stability and longevity.
