Dormakaba J12 693 – Frequently Asked Questions

1) Will the Dormakaba J12 arm work with any door closer, or only the ED900?
The J12 arm is built for Dormakaba ED900 Series door closers only. It is a genuine replacement arm for that family, so if your closer body is a different Dormakaba series or another brand, the J12 will not give you the correct mechanical fit at the closer spindle.
2) What mounting position is the J12 closer arm for, push side or pull side?
Push side, top jamb mount. The closer body sits on the frame face above the door and the arm reaches back to the door on the push face. If your closer is mounted on the door with the arm to the frame stop (regular arm, pull side), the J12 is the wrong arm for that setup.
3) What does the reveal on a top jamb door closer arm mean, and which reveal sizes does the J12 come in?
Reveal is the setback between the face of the door and the frame or soffit the closer is mounted to. A top jamb closer needs an arm geometry that spans that gap or the closer cannot reach its full arc. The J12 is offered in a 12 inch reveal version and an 8 inch reveal version, so measure the actual reveal on your opening before choosing.
4) What do I have to specify when ordering a Dormakaba J12 arm?
Three things: reveal, size, and finish. The 12 inch reveal version is paired with an 8 inch size, and the 8 inch reveal version is paired with a 0 inch size. Finishes are 689 aluminum, 693 black, and 695 dark bronze. The 12 inch reveal is available in all three finishes; the 8 inch reveal comes in 693 black and 695 dark bronze.
5) My ED900 closer body is fine but the arm is bent. Do I need a whole new closer?
No. The J12 is sold as a standalone replacement arm for existing ED900 Series installations, so a damaged or bent push-side top jamb arm can be swapped without replacing the closer body. Order the same reveal and finish as what came off the door.
6) I manage a building with mixed door finishes. Can I match the J12 arm to existing Dormakaba closers?
Finish options on the J12 are the standard architectural closer finishes: 689 aluminum, 693 black, and 695 dark bronze. Those are the same number codes used on closer covers, so matching the arm to the cover already on the frame is a matter of ordering the same code. Note the 689 aluminum is offered on the 12 inch reveal version.
7) Why would I use a top jamb mount arm instead of a parallel arm closer setup?
Top jamb mounting puts the closer on the frame face above the door rather than on the door itself, which is the way to go when the door leaf has no room for a closer or the head stop geometry rules out a regular or parallel arm. The J12 covers that case on the push side, with reveal geometry that handles the offset between door face and frame.
8) Is the J12 arm rated for commercial traffic or is it a light duty part?
It is a commercial part, catalogued as a replacement arm for commercial door closer service, and used in offices, schools, healthcare, retail, warehouses, multi-tenant residential, and government buildings. It is not a residential-grade accessory.
