There are two advantages to buying our Door Closer Bodies with Mounting Clips. The first is if you are only replacing a worn out Door Closer, you will reduce your costs by not purchasing unnecessary hardware. The second is that by adding accessories you can get a Door Closer with the exact accessories you need for the job you are doing. Just select a Door Closer and add the different accessory parts (Pivots, Arms, etc.) you need to create the Door Closer package of your choice. Each Door Closer Body comes packaged with Mounting Clips, Templates, and Instructions.


Independent Adjustment Valves
Non-Critical valve control adjusts both Closing Speed and Latching Speed independent of each other.

Special Retaining Rings Prevent the Adjustment Valve Screws from being backed all the way out of the Door Closer Body.

NOTE: An auxiliary floor or overhead door stop is recommended to prevent possible damage to both the door closer and entry way due to over-extension of maximum allowable door swing.
