What is a Spring Hinge?
Definition of Spring Hinge in Construction A spring hinge is normally a standard butt hinge that has a spring installed within the pivot mechanism of the hinge. This spring is adjusted by an allen wrench, with the hex receptacle normally located at the top of the hinge assembly. Spring hinges are designed to force the closing of an open door by applying a spring pressure within the internal workings of the spring itself. The opening of the door basically charges the spring and once the door is allowed to return to its closed position, the spring will force the door closed. A spring hinge is normally used on dressing room doors, specialty doors that must be closed at all times, closet doors, etc. A spring hinge is a less expensive alternate to keeping the door closed than the installation of a full closure assembly. Spring hinges are available in different strengths and sizes and are designed for doors of all weight and size.
