Product Introduction Product Feature Technical Specification Comments

A door closer is a mechanism—typically installed at the top of the door—designed to close the door and prevent it from shutting forcefully or slamming. A door closer is a mechanism designed to control the speed at which a door closes. It operates using a torsion system that builds up tension when the door is opened. Upon release, this stored tension gently returns the door to its closed position while regulating its movement speed. These devices also serve as a safety feature, helping to prevent the door from slamming against the frame. Furthermore, this seemingly small device provides peace of mind regarding door closure, eliminating the need for additional surveillance cameras to monitor the area. Ultimately, door closers are highly practical and useful, finding widespread application in both public and residential settings. The weight of the door is also a crucial factor when using a door closer. This model is designed for lightweight doors and supports a weight of up to 80 kg.
