Sargent 351A EN – Frequently Asked Questions

1) What is the Sargent 351A and what is it used for?
The Sargent 351A is a top jamb mounting plate for the 351 Series door closer hardware. It gives the closer a solid attachment point on the head frame when the closer is mounted in the top jamb position, holding alignment and spreading the load on the frame. It is a mounting accessory, not a closer, so you order it alongside the 351 Series closer it serves.
2) Will the Sargent 351A mounting plate work with a closer from another series?
No. The 351A plate is built for 351 Series hardware and should be matched to that series. If your closer is from a different Sargent family, use the mounting plate called out for that family rather than forcing this one to fit.
3) When do I need a top jamb mounting plate instead of mounting the closer directly to the frame?
Top jamb mounting puts the closer body on the face of the head frame. A plate like the 351A is what you use when the frame face will not take the closer screws directly, when the frame is not reinforced at the fastening points, or when you want a consistent, repeatable fastening pattern across a run of openings. If your frame is already reinforced and prepped for the closer, you may not need the plate at all.
4) What finishes does the Sargent 351A top jamb plate come in?
Five sprayed enamel finishes: EAB sprayed brass enamel, EN sprayed aluminum enamel, EP sprayed bronze enamel to match satin bronze, EB sprayed bronze enamel to match dark satin bronze, and ED sprayed bronze enamel to match dark statuary bronze. Pick the same code as the closer so the plate and closer body read as one unit on the frame.
5) Is the Sargent 351A rated for heavy traffic commercial openings?
It is a Grade 1, heavy duty commercial component. That is the top ANSI/BHMA grade tier, which is what specifiers normally require for schools, hospitals, and other high traffic institutional openings.
6) Does using the Sargent 351A plate affect ADA compliance on the opening?
The 351A is listed as ADA compliant, so adding it to a top jamb closer installation does not put the opening outside ADA requirements. Compliance on the door itself still depends on how the closer is adjusted for opening force and closing speed.
7) Does the Sargent 351A include a delayed action feature?
No. The 351A is a mounting plate with no delay function. Delayed closing is a function of the closer itself, so if your opening needs extra time for wheelchair or cart traffic, specify a 351 Series closer with that feature rather than looking for it in the mounting hardware.
8) I manage a building with mixed frame finishes. Can I standardize on one Sargent 351A plate?
You can standardize on the 351A part itself across all your 351 Series top jamb closers and just change the enamel code per opening. Aluminum enamel (EN) covers aluminum and painted frames, and the three bronze enamels (EP, EB, ED) let you match satin, dark satin, or dark statuary bronze hardware already on the building.
