Sargent 25O8 26D – Frequently Asked Questions

1) What does the mortise foot on the 25O8 arm mean for mounting?
Mortise foot means the arm's shoe seats into a recessed (mortised) mounting interface rather than surface-mounting flat to the frame or door. You need that mortise prep already present, or you have to cut it. If the existing arm on your opening uses a plain surface-mounted shoe, the 25O8 is not a like-for-like swap.
2) What finishes does the Sargent 25O8 closer arm come in?
Six finishes: 03 Bright Brass clear coated, 04 Satin Brass clear coated, 10B dark oxidized satin bronze oil rubbed, 26 bright chromium plated over nickel, 26D satin chromium plated over nickel, and BSP black suede powder coat. Pick the one matching the closer cover and the rest of the trim on the opening, 26D and 10B being the usual choices on commercial jobs.
3) I'm standardizing closers across a building. Can I order one 25O8 arm finish for all my Sargent closers?
You can standardize on one finish across 351, 281 and 1431 Series closers, since the same 25O8 arm covers all three series and all six finishes are offered on it. The constraint is the mounting: each opening needs the mortise foot prep this arm uses. Openings with a different closer series or a surface-mount shoe need a different arm.
4) Do I need anything else besides the 25O8 arm to get the closer working again?
The 25O8 is the arm assembly with mortise foot. If the failure was only the arm (bent forearm, stripped shoe, sheared main arm), this restores function on a 351, 281 or 1431 closer. If the closer body itself is leaking oil or has lost hydraulic control, an arm will not fix it and you need a new closer.
5) Can I use the Sargent 25O8 arm on a residential door closer?
It is a commercial-grade part. The 25O8 is intended for high-traffic commercial and institutional openings, and it only fits Sargent 351, 281 and 1431 Series closers, which are commercial closers. For a light residential closer, look at a residential unit instead of trying to match this arm.
6) Is the 25O8 a genuine Sargent part or an aftermarket arm?
Genuine Sargent, built to OEM specification for 351, 281 and 1431 Series closer assemblies. That matters on a maintenance contract where the closer body has to keep performing to its original spec after the arm is replaced.
