Sargent 25PH4 26D – Frequently Asked Questions

1) Which Sargent door closers does the 25PH4 arm fit?
The 25PH4 arm is built for Sargent 351, 281 and 1431 Series door closers. It goes on as a direct-fit replacement on those bodies, so you are not drilling or adapting anything to make it sit right. If your closer body is from a different Sargent series, this is not the arm for it.
2) What does the PH in Sargent 25PH4 mean, and is this the right arm for a parallel arm installation?
PH here is the parallel hold open configuration. The 25PH4 is set up for parallel flush frame mounting with hold open, meaning the closer mounts on the push side with the arm running parallel to the door and the frame bracket landing flush on the frame face. If your closer is mounted on the pull side in a regular arm arrangement, this arm will not suit that installation.
3) Will the 25PH4 hold a door open, and where is that useful?
Yes, hold open is part of what this arm does. It keeps the door standing at a set open position instead of closing every cycle, which is what building managers want for move-ins, deliveries, classroom and corridor doors, and accessibility situations in offices, schools, healthcare, retail and municipal buildings. One caution from the trade side: a mechanical hold open arm should not go on a fire rated opening that has to self-close and latch.
4) Do I have to replace the whole door closer, or can I just swap the arm?
If the closer body still holds oil and controls the door, you only need the arm. The 25PH4 is sold as a replacement part for the 351, 281 and 1431 Series, so a bent, seized or missing parallel hold open arm can be changed out without pulling the closer off the door. That is the usual MRO fix when a door has been forced past its stop.
5) What finishes can I get the Sargent 25PH4 closer arm in?
Seven finishes: EN sprayed aluminum enamel, BSP black suede powder coat, 26 bright chrome over nickel, 26D satin chrome over nickel, 10B dark oxidized satin bronze oil rubbed, 03 bright brass clear coated, and 04 satin brass clear coated. For a property manager matching a run of openings, 26D and EN are the two that blend with most standard commercial closer bodies; specify the same code across the building so replacements stay consistent.
6) Is the 25PH4 closer arm handed?
Ordering is by configuration and finish only, not by hand. You pick the parallel flush frame hold open arm in the finish you need. What does have to match is the closer series (351, 281 or 1431) and the mounting arrangement already on the opening, so check the closer body label before you order.
7) Is the Sargent 25PH4 arm rated for commercial traffic or is it a residential part?
Commercial. The 25PH4 is part of Sargent's commercial door closer parts line, built for heavy-use openings in offices, schools, hospitals, warehouses and multi-tenant residential buildings rather than light interior residential doors.
