Adjustable Power Standard Installation Jamb Bracket
Provides a ±7-1/2% power adjustment by relocation of the forearm pin in the jamb bracket. Supplied
standard with all standard installation and corner bracket installation non-hold open closers.

Hold Open Arms
Permit door to be held open at any point between 90° and 180° by using different closer mounting locations.
Hold open arms are non-handed for standard arm and corner bracket installations. Hold open arms are
handed for parallel arm and rigid parallel arm installations.

Field Reversible
Closer spring can be reversed to accommodate the hand of the installation when arms are non-handed. To
save time and costs on the job site, it is recommended to order the closer for the proper hand of door. Delayed action closers are not reversible.

Adjustable Delayed Action Closing
Closer’s initial closing speed at the beginning of the closing cycle (from full open down to approximately 70°) is adjustable, allowing slow-moving traffic to pass through the opening before the closer begins its normal closing speed. For regular arm non-hold open closers only. Delayed action closers are handed. They are not available with backcheck cushioning.
