Uniquely Design Door Closers

Slide track surface mounted door-closers use a single arm, which moves on a slide and the energy is stored in a spring, when the door in pushed or pulled open. This energy is then used to close the door, when the pressure is released.The non-track surface door-closer uses a uniquely designed arm, which is divided into two pieces with a spring mechanism. Again, the energy is stored in the spring and is used to restore the door back to its closed position.  Door Closers are generally used for doors, which will always open in one direction.  Concealed in frame type Entrance-closers are generally used in doors that are supposed to open both ways. However, the installation of such entrance-closers needs to be pre-planned as they are placed inside the frame of the door. These are generally used in hospitals and hotels, where people might open the doors either inwards or outwards. For more information please visit “Door Closers” lvk
