These hardware components are designed to automatically return a door to its closed position after it has been opened. They are typically mortised or surface-mounted to doors and frames and employ a spring mechanism to provide the closing force. A common application is on cabinet doors in residential kitchens.
The implementation of this type of hardware contributes to enhanced safety by preventing doors from being left ajar, which can be especially crucial in areas frequented by children or pets. Moreover, they can aid in energy conservation by ensuring doors remain shut, thus minimizing drafts and maintaining consistent temperatures within enclosed spaces. Historically, mechanisms for automated door closure have been employed in various forms, evolving from simple weights and pulleys to the sophisticated spring-loaded designs available today.
