CRL Adjustable Spring Power Overhead Concealed Door Closer
is available to meet A.D.A. Opening Force requirements. Available as a body only with mounting clips to retrofit existing non-adjustable door closer installations, and as complete packages that includes the Door Closer, Mounting Clips, Type S-Side Load Arm or Type A-End Load Arm, and a DP-Adjustable Dual-Purpose Bottom Pivot Set or GE-Pivot Set. The Door Closer has independent, dual-action valves to control closing and latching speeds. Both 90º and 105º Hold Open and No Hold Open models are available. Door Closer Bodies fit into standard 1-3/4″ x 4″ (44 x 102 mm), or larger, extrusions. Door Closers with different spring sizes or hardware options are available.
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.
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. Important Notes: 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.
