Structure of the Ground Spring

The ground spring is done by pressing the spring with a turbine unit to close the door. The ground spring is divided into two parts, the ground shaft is fixed to the door frame, the sky shaft is used to connect the door fan and the door frame, through the release of spring pressure to push the sky shaft, so that the door can be freely closed.

The basic configuration of the ground spring is the sky axis and the ground axis (or ground foot). The sky shaft is an accessory that connects the door frame and door fan in the upper part, consisting of a bolt-adjustable pin-type shaft fixed to the door fan and a bushing fixed to the door fan. The sky shaft can be applied to almost all wooden, steel, aluminum and glass doors and frameless glass doors using glass door clips.
