Dormakaba MOD AF89J 689 – Frequently Asked Questions

1) What reveal does the Dormakaba MOD AF86J top-jamb arm cover?
The MOD AF86J is built for reveals from 4 to 8 inches. Reveal is the distance from the face of the door to the face of the frame stop where the closer body mounts on the frame. Measure that gap on your opening first: under 4 inches or over 8 inches and this arm is the wrong one.
2) Which Dormakaba closer series does the MOD AF86J arm fit?
Order it for either the 8600 or the 8900 series closer. Both series are available, and the arm is a genuine Dormakaba modular component matched to those closer bodies, so pick the series that matches the closer already on the door.
3) Will this arm hold the door open?
No. The AF86J is a non-hold open arm, so the door returns to the closed and latched position every cycle. If your opening needs the leaf to stay parked at a set degree, you need a hold-open arm instead, not this one.
4) Can I swap this closer arm without replacing the whole closer?
That is the point of the modular design. The AF86J is sold as a field replacement arm, so a bent or seized arm can be changed out without pulling the closer body off the frame. Keep the series (8600 or 8900) and the reveal range in mind when you order.
5) When should I use a top-jamb arm instead of regular or parallel arm mounting?
Top jamb puts the closer body on the face of the frame above the door rather than on the door itself or under the soffit. It is the choice when the door face cannot take the closer or when there is no usable soffit depth for a parallel arm. The flat AF86J covers that configuration for 4 to 8 inch reveals. If the closer is going on the pull-side door face, that is a regular arm application, not this arm.
6) What finishes does the Dormakaba MOD AF86J arm come in?
Three: 689 aluminum, 693 black, and 695 dark bronze, and all three are offered for both the 8600 and 8900 series. For a building where the other openings already carry a painted aluminum closer, 689 is the usual match.
7) My reveal is only 2 inches. Is this the right Dormakaba arm?
No. The AF86J starts at a 4 inch reveal. At 2 inches you need a top-jamb arm rated for a shorter reveal, or a different mounting approach altogether. Measure from the door face to the frame face at the hinge side and match that number to the arm's stated range before ordering.
8) Is the MOD AF86J arm suitable for high traffic commercial doors?
It is a commercial-grade component, catalogued for commercial rather than residential use, and Dormakaba lists it for office buildings, schools, healthcare, retail, government, industrial and multi-tenant residential openings. For a property manager standardizing corridor and stairwell doors, the non-hold open action keeps every leaf latching on its own.
