Common questions about manuals, registration, and support for this brand.
Using a hex wrench (typically 1/8"), turn the adjustment valves located on the closer body. Turning clockwise generally slows the closing speed, while turning counter-clockwise increases it. Refer to the specific model template for valve locations.
Check the door alignment and ensured the strike plate is not binding against the latch. If the lock mechanism itself feels stiff, verify that the through-bolts are not over-tightened, as this can compress the chassis.
Most SARGENT surface closers, such as the 351 and 1431 series, are non-handed and can be installed on left or right-hand doors. However, specific arms (like the PH10 holder arm) may be handed.
