What is a Door Spring Hinge

A door spring hinge, also known as an automatic door hinge or self-closing hinge, is a specialized hardware device designed to automatically close a door after it has been opened. Unlike standard hinges, which simply allow the door to swing open and shut, spring hinges incorporate a built-in spring mechanism that provides tension to return the door to its closed position. This mechanism is typically contained within the hinge knuckles and can be adjusted to control the closing speed and force. Door spring hinges are commonly used in residential, commercial, and industrial settings to ensure doors close securely for safety, energy efficiency, and convenience. They are particularly prevalent in areas where fire codes require self-closing doors, such as in stairwells, garages, and between rooms where privacy or climate control is needed. The design varies, including single-action spring hinges for standard doors and double-action versions for doors that swing both ways, often seen in restaurants or kitchens. Installation usually involves replacing existing hinges with spring-loaded ones, and adjustments can be made via set screws to tailor the closing tension to the door's weight and usage frequency. Overall, door spring hinges offer a practical solution for automating door closure without the need for additional hardware like door closers.
