Dormakaba MOD ISJH 689 – Frequently Asked Questions

1) What is the difference between a top jamb closer arm and a parallel arm, and when do I need the top jamb version?
A top jamb arm mounts the closer body on the face of the frame header above the door with the arm reaching back to the door face, so it is what you use when the door has no room for a body-on-door regular or parallel arm mount, or when the door swings out away from the closer. The MOD ISJH is built specifically for that top jamb condition and for frames with a deep reveal, up to 6-1/2 inches. If your closer body is already mounted on the door and pulls to the frame stop, you need a parallel or regular arm instead, not this one.
2) Does the MOD ISJH arm include a hold open, or do I need a separate hold open device?
Hold open is built into the arm. The MOD ISJH is a heavy-duty cushion hold open arm, so the door stays put at the set open position and the cushion stop absorbs the swing at the end of travel. No separate overhead stop or hold-open accessory is required for that function.
3) Can I buy just the closer arm, or do I have to replace the whole Dormakaba closer?
The arm can be bought on its own. MOD ISJH is a genuine Dormakaba replacement part within the modular closer arm system, so a bent or failed arm on a compatible Dormakaba closer body can be swapped without pulling and reinstalling the whole unit. Confirm your existing closer is one of the Dormakaba modular bodies before ordering.
4) What finishes does the Dormakaba MOD ISJH closer arm come in?
Three finishes: 689 aluminum, 693 black, and 695 dark bronze. Those are the standard painted closer finishes, so matching the arm to existing Dormakaba closers on adjacent openings in a building is usually straightforward, pick the code already on the covers you have.
5) Is the MOD ISJH arm suitable for a high-traffic entrance, or is it a light-duty part?
It is a commercial-duty part, not residential. The cushion mechanism is heavy-duty and the arm is intended for high-use openings, offices, schools, healthcare, retail, warehouses, government buildings, and multi-tenant residential corridors. The cushion stop is what protects the arm and frame when traffic throws the door open hard.
6) Will the MOD ISJH fit an older Dorma closer, or only current Dormakaba models?
The arm is listed as a Dorma door closer part and accessory and is built for the Dormakaba modular closer platform, so it fits the modular Dorma/Dormakaba closer bodies that take an interchangeable arm. It is not a universal arm, a closer from another manufacturer will not accept it.
7) Is a cushion hold open arm the right choice if the door needs to close every time for fire or smoke separation?
No. A mechanical cushion hold open arm holds the door open until someone pushes it shut, which defeats a self-closing opening. On a labeled fire or smoke door, specify a non-hold-open arm or an electromagnetic hold open tied to the alarm instead. The MOD ISJH is the right pick on non-rated openings where staff want the door parked open and want the swing cushioned at the stop.
