A door closer is a mechanical device that closes a door - in general after someone opens it, or after it was automatically opened. There are four styles of interior door closer: surface-mounted, concealed in frame, concealed in the floor, and concealed indoor. Our JY door closers are mainly surface-mounted. With both closing and latching speeds independently adjustable, they will satisfy the requirements for smooth operating door control. They have adjustable backcheck features that help prevent damage to the closer, door, and adjacent surface when the door is violently swung open due to wind or heavy pedestrian traffic.
