Door Closer

A door closer is a mechanical device that automatically closes a door after it has been opened. It is commonly used in commercial, residential, and public buildings to ensure doors close securely and reduce the spread of fire and smoke, enhance security, and improve energy efficiency by minimizing air leakage.

Door closers come in various types, including surface-mounted, concealed, floor-spring, and hydraulic versions, each designed for specific door applications like glass doors, wooden doors, and metal doors. Modern door closers often feature adjustable closing speed, latching action, and back-check to provide customizable control over how the door operates.

Popular in settings such as offices, hotels, shopping malls, and hospitals, door closers contribute significantly to the safety, convenience, and maintenance of doorways.
