Understanding Surface Door Closers

Surface door closers, often referred to as door closers or overhead door closers, are mechanical devices that control the opening and closing of doors, typically installed on the surface of the door and frame. These closers consist of a hydraulic mechanism that controls the speed and force with which the door closes. Key features of surface door closers include:

Closing Speed Control: Surface door closers allow users to adjust the closing speed to ensure that doors close gently and securely.

Latching Speed Control: They also enable control over the latching speed, which is the speed at which the door securely engages with the frame.

Delayed Action: Some surface door closers offer a delayed action feature, allowing the door to close more slowly at first to accommodate individuals with limited mobility.

Hold-Open Feature: Certain closers have a hold-open option that allows the door to remain open at a specific angle until manually closed.
