The gate closer DIREKT operates directly on the gate/door without the help of any lever. It is fixed with one end to the gate post or the door frame and with the other to the door or gate itself.

It operates similarly to a gas spring. When the gate is open, the piston rod of the gate closer is compressed and the pressure of the gas inside the gate closer acts on the piston. The piston rod extends and closes the door/gate. The cylinder of the gate closer contains hydraulic oil, which results in a controlled closing speed that is slowed down. By using nitrogen instead of a helical spring, much higher closing forces can be achieved. Thus the gate closer DIREKT always closes the door/gate reliably despite its small diameter.
