Sargent Door Closer Parts
Sargent door closer parts let you repair a Sargent closer instead of replacing it. Shop 25 Series arms such as the 25P9 standard parallel arm and 25CPS compression stop arm, drop and mounting plates like the 351D, brackets, the 581-2 blade stop spacer, screw packs and touch-up paint. Complete closers are in Sargent door closers.
Match the part to your Sargent closer series
Sargent closer parts are listed for the closer series, so read the series on the closer body before ordering. The catalog covers the 281, 351, 1131 and 1431 Series. Arms in the 25 Series fit several closers, while drop plates and mounting plates are made for one series, such as the 351D for the 351 Series or the 281D for the 281 Series. The finish code EN means sprayed aluminum.

Stop arms: positive stop vs compression stop
A stop arm limits how far the door opens so it does not hit a wall or strain the hinges. A positive stop (PS, PSH) stops the door firmly at the set angle, while a compression stop (CPS, CPSH) cushions the stop with a spring. The H versions add hold open. On fire doors that must close by themselves, use a stop arm without hold open, or a hold-open device that releases on alarm.
Drop plates, mounting plates and brackets
Plates and brackets fix mounting problems. The 351D drop plate lets a parallel arm 351 Series closer mount on a door with a narrow top rail; its listing says it requires a 3" (76 mm) minimum top rail. The 281B and 351B are mounting plates for top jamb applications with low ceilings, the 281D is a drop plate for the 281 Series and the 1431B a mounting plate for the 1431 Series. Brackets include the 125P9 and 125PH9 parallel arm foot brackets, the 125V narrow frame bracket and the 125VF flush frame bracket.
Blade stop spacers and small parts
Frames with a 1/2" blade stop push the parallel arm shoe away from the frame, so Sargent lists blade stop spacer kits: the 581-1 and 581-2, listed for frames with 1/2" blade stops and for use with P10, PH10, PS, PSH, CPS and CPSH arms, with a 125-V bracket included. Small parts include the 63-2607 main arm and link assembly, 63-0191 arm spacer and 63-2391 screw pack. Sargent spray paint is listed in aluminum (EN), dark bronze (EB), bronze (EP) and brass (EAB) for touching up closers.
Can door closers be repaired?
Many closer problems are repaired with parts: a bent arm, a broken shoe, a missing screw or a closer that needs a plate or spacer to mount properly. If the closer body leaks oil or the door slams even after adjusting the valves, the body has usually failed and the closer should be replaced. Arms can often be reused on a new body of the same series.

Frequently Asked Questions
What are the parts of a door closer called?
A surface door closer has a body (the cylinder with oil and spring), an arm with a main arm and forearm, a shoe or bracket on the frame or door, mounting plates when needed, and a cover. Sargent lists arms, plates, brackets, spacers and screw packs separately.
Do Sargent closer arms fit other brands?
No. Sargent 25 Series arms are made for Sargent closers and are not designed to fit LCN, Norton, Falcon or other brands. Match the arm to the Sargent series named on the closer body, and check the mounting (regular, top jamb or parallel) before ordering.
What do the Sargent closer finish codes mean?
In the listings, EN is sprayed aluminum, EB dark bronze, EP bronze and EAB brass, as shown on the Sargent spray paint products. Order arms, plates and paint in the same finish as the closer for a matching installation.
