Accentra 400-1B 693 – Frequently Asked Questions

1) Which Accentra door closers does the 400-1B top jamb arm assembly fit?
The 400-1B JL top jamb arm assembly is built for Accentra 51, 3000 and 4400 Series door closers. It is an original-specification replacement arm, so if the closer body on the door is one of those three series and it is mounted top jamb, this is the arm that goes back on it. It will not serve as an arm for closers outside those series.
2) Is the Accentra 400-1B arm a hold-open arm?
No. The 400-1B is configured non-hold open, so the door closes fully every time under closer control. If the opening needs the door to stand open at a set point, this arm is the wrong part for that job, you need a hold-open version of the arm instead.
3) What mounting position does a JL top jamb arm work in?
Top jamb mounting: the closer body sits on the frame face above the door and the arm reaches back to the door face. The 400-1B is built for that geometry only. If the closer on your opening is mounted on the door (regular/pull side) or on the frame soffit (parallel arm), the arm for that configuration is a different part.
4) What finishes does the Accentra 400-1B arm come in to match my existing closers?
Twelve finishes, covering both plated and painted options: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 bright chrome, 626 satin chrome, and painted 689 aluminum, 690 dark bronze, 691 light bronze, 693 black, 694 medium bronze and 696 satin brass. For a fleet of doors, order to the BHMA number already on the closer body rather than by finish name.
5) Can I just replace the arm instead of the whole door closer?
Yes, if the closer body and its fasteners are sound and the failure is in the arm linkage. The 400-1B is sold as a standalone arm assembly for top jamb, non-hold open use on 51, 3000 and 4400 Series closers, so a bent or worn arm can be swapped without pulling the closer body off the frame.
6) Is the 400-1B closer arm rated for commercial traffic?
It is a commercial-grade part, made to Accentra specification as a direct replacement component for their 51, 3000 and 4400 Series closers. Typical use is office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and municipal buildings.
