Adjustable Spring Power
Allows adjustment of spring tension from a minimum of 8-1/2 lbs. opening force to a medium spring size to accommodate site conditions and requirements.

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.


Product Warning:

Closers set to comply with A.D.A. specified opening forces might not provide adequate spring power to control and close the door due to varying site conditions and door size.
