Instructions to Install a Security Door Pneumatic Closer

A pneumatic door closer is a door-closing device that works by using compressed air in a cylinder to control the closing arm attached to the door. These closers are often attached to security doors to make sure the door closes properly when not in use. These closers pull the door shut to ensure security and help it to close smoothly and tightly. Pilot holes are drilled on both the door and the jamb for two brackets and the closer's pneumatic arm attaches to the brackets.

  Attach the frame arm to the jamb bracket, inserting the pin through both the bracket side end of the closer arm and the appropriate spot on the bracket to secure it into place. Attach the door bracket to the other end of the closer arm.
