Sargent 25H8 26D RH – Frequently Asked Questions

1) Will the Sargent 25H8 arm fit my door closer, or do I need to know the series first?
The 25H8 is built for Sargent 351, 281 and 1431 Series closers. If the closer body on your door is one of those three, the arm mounts as a direct replacement with no modification to the closer. Any other Sargent series, or another manufacturer's closer, needs a different arm.
2) Is the 25H8 closer arm handed, and what happens if I order the wrong hand?
Handing matters here. The 25H8 RH is configured for right-hand openings, and the mortise foot hold-open will not align correctly on a left-hand door. Determine the hand from the hinge side standing outside the door before ordering; a right-hand door has hinges on your right and swings away from you.
3) Can I just replace the arm instead of the whole door closer?
Yes, if the closer body still holds oil and controls the sweep. The 25H8 is an OEM-level replacement arm for 351, 281 and 1431 Series closers, so a bent arm or a failed hold-open foot can be corrected without pulling the closer off the door. If the body is leaking or the closing speed can no longer be adjusted, replace the closer instead.
4) What does a mortise foot hold open arm actually do on a commercial door closer?
The mortise foot is the shoe at the door end of the arm that engages to hold the door open at a chosen position, so traffic, carts or moving crews can pass without someone propping the door. The closer still controls closing once the hold-open is released. It's the part that typically wears or gets bent, which is why it's sold as a standalone replacement.
5) What finishes does the Sargent 25H8 hold open arm come in?
Six finishes: 03 bright brass clear coated, 04 satin brass clear coated, 26 bright chromium over nickel, 26D satin chromium over nickel, 10B dark oxidized satin bronze oil rubbed, and BSP black suede powder coat. For a fleet of openings, 26D is the usual match to satin chrome lever trim and 10B to oil-rubbed bronze, so you can bring a repaired closer back in line with the rest of the hardware on the floor.
6) I need hold open on a pair of doors. Do I order two 25H8 arms?
No. A pair of doors is one right-hand leaf and one left-hand leaf, so you'd order one 25H8 RH for the right-hand door and the left-hand version of the same arm for the other leaf. The 25H8 RH covers a single right-hand opening only.
7) Is this arm rated for high-traffic commercial use or is it a residential part?
It's a commercial part. Sargent lists the 25H8 as commercial grade, and it's used on office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential and government buildings, all places where the hold-open cycles many times a day.
