Door Closer

Surface door closers mount to the surface of the door and frame and close the door through an arm linkage. Surface door closers are popular because they are easy to install and service.

Regular arm application places the closer on the hinge side of the door. As the door opens, motion is transmitted through the arm, which compresses the closer spring. When the door is released, the power stored in the spring closes the door by transmitting the motion back through the arm, which is attached to the frame.

Parallel arm closers also mount on the side of the door opposite from the hinge side (stop side). The closed arm position is parallel to the door, which is the reason for its name.

With the top jamb application, the door closer is attached to the frame face above the door on the side opposite the hinges (stop side). The closer arm is attached to the door. The mechanical operation is similar to that of a regular arm closer.
