Dormakaba MOD AR86 689 – Frequently Asked Questions

1) Will the Dorma MOD AR86 closer arm work on a left-hand door?
The MOD AR86 arm is non-handed, so the same arm goes on a right or left hand door. No handing to specify when you order, and one part covers both swings if you're stocking spares for a building with doors going both ways.
2) Which Dorma closers does the MOD AR86 arm fit?
It's the round-form standard arm for Dorma 7000 and 8600 series closers, and it's an optional arm on the 8600 Series. If the closer body on the door is from another Dorma family or another brand, this arm is not the replacement.
3) Will the MOD AR86 arm hold the door open?
No. It's a non-hold-open arm, so the door closes every time. If you need the door to stay open at a set point, this is the wrong arm to order.
4) Do I get the whole arm or just the main forearm section?
It ships as a complete arm assembly, not a single link. That means the main arm and the forearm with the shoe, so you're not sourcing pieces separately to put a closer back in service.
5) What finishes does the Dorma MOD AR86 arm come in?
Three: 689 anodized aluminum, 693 black, and 695 dark duranodic bronze. Those are the standard architectural finish codes, so if the other closers in the building were specified 689, ordering 689 here keeps the openings matching.
6) Can I use the MOD AR86 for a regular arm mount on the pull side, or is it top jamb only?
Both. It covers regular arm and top jamb installations, and the 0 to 4 inch reveal range is what makes the top jamb application work. Same arm either way, so you don't order a different part when one opening is pull side and the next is push side top jamb.
7) Is the Dorma MOD AR86 arm rated for commercial door traffic?
It's a commercial door hardware part, sold as a replacement part for Dorma door closers rather than a residential-grade item. Typical use is swapping a bent or seized arm on an existing 7000 or 8600 closer in a commercial opening.
