A hinge incorporating an integral spring mechanism that automatically returns the door to the closed position. Self-closing hinges can replace door closers in some applications, particularly fire doors.
Spring hinges are sized by the number of springs and spring strength, correlating to door size and weight. Typically two or three spring hinges are required, with remaining hinge positions using matching non-spring hinges. Adjustable tension models allow field tuning.
Self-closing hinges meet NFPA 80 requirements for fire door self-closing when properly sized. They provide cleaner aesthetics than surface-mounted closers but offer less closing speed control. Not suitable for barrier-free/accessible egress due to lack of delayed action. Related: butt hinge, door closer. Shop self-closing hinges.
