Accentra 400-3A 626 – Frequently Asked Questions

1) Which Accentra door closers does the 400-3A top jamb arm fit?
The 400-3A J top jamb arm assembly is built for Accentra 51, 3000 and 4400 Series door closers. It's a genuine replacement arm for those closer bodies, so if the closer on your door is one of those three series, the arm mounts to it without adapters. For any other closer series or brand, it is not the right arm.
2) What is a top jamb arm and when do I use it instead of a regular or parallel arm?
A top jamb mount puts the closer body on the face of the frame above the door, with the arm reaching back to the door face. You use it when the closer cannot go on the door itself, for example narrow top rails, aluminum or glass door conditions, or where the push side is the only surface available. Regular arm mounts the closer on the pull-side door face; parallel arm mounts on the push-side door face with the arm running along the frame. The 400-3A is the top jamb configuration for the 51, 3000 and 4400 Series, so order it when neither of those other two mounting positions works on your opening.
3) Does the Accentra 400-3A arm hold the door open?
Yes. The 400-3A is the hold-open version of the top jamb arm, so the door can be swung to an open position and stay there until it's pushed back. That's the usual choice for loading doors, corridors and other high-traffic openings where staff need the door parked open. Note that a hold-open arm is generally not acceptable on a fire-rated opening unless the hold-open is part of an approved release device.
4) Is the 400-3A arm a complete door closer or just the arm?
Just the arm. It is a replacement arm assembly only, no closer body, no hydraulic unit. You need an existing Accentra 51, 3000 or 4400 Series closer already on the opening, or a new closer ordered separately. Buy this when the arm is bent, the hold-open has quit, or you're converting an existing closer to a top jamb hold-open application.
5) What finishes does the Accentra 400-3A top jamb arm come in?
Twelve finishes: 605 Bright Brass, 606 Satin Brass, 612 Satin Bronze, 613 Oil Rubbed Bronze, 625 Bright Chrome, 626 Satin Chrome, 689 Aluminum Painted, 690 Dark Bronze Painted, 691 Light Bronze Painted, 693 Black Painted, 694 Medium Bronze Painted and 696 Satin Brass Painted. If you are replacing one arm in a building where the rest are standardized, match the BHMA number stamped or specified on the existing closer rather than eyeballing the color, since 690 and 694 in particular read close.
6) Can I use the 400-3A to convert my existing Accentra closer from parallel arm to top jamb mounting?
On a 51, 3000 or 4400 Series closer, yes, the arm itself is the top jamb configuration for those bodies. What changes is the prep: top jamb mounting needs the closer body fastened to the frame face above the door and the shoe fastened to the door face, which is a different hole pattern than a parallel arm install. Plan on new holes in the frame and door, and confirm you have the frame face width above the opening to take the closer body.
7) I need the same arm without hold open. Is the 400-3A the right part?
No. The 400-3A is specifically the hold-open version of the J top jamb arm. If you want the door to close every time with no parked position, order the non hold-open top jamb arm for your 51, 3000 or 4400 Series closer instead. This is the usual decision point on fire-rated and smoke-barrier doors, where a free-swinging hold-open is not permitted.
8) Is this arm rated for commercial traffic or is it a residential part?
Commercial. The 400-3A is specified as commercial-grade door closer hardware, and the typical applications are office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and government facilities. It is the right class of part for an MRO stockroom standardizing on Accentra closers.
