Dormakaba MOD AO8P 689 – Frequently Asked Questions

1) Which Dormakaba door closers does the MOD-AO8P arm fit?
The MOD-AO8P modular closer arm is built for Dormakaba 8600 and 7400 Series door closers. It is a manufacturer replacement arm for those two families only, so if the closer body on the door is a different Dormakaba series or another brand, this arm is not the part to order.
2) Will the MOD-AO8P hold the door open?
No. The MOD-AO8P is a non-hold-open arm, so the door closes fully every cycle. If the opening needs to stay propped, you need a hold-open arm instead, not this one. Non-hold-open is the right choice on fire rated and egress doors that have to self-close.
3) What comes in the MOD-AO8P Tri-Pack, and do I need to buy a bracket separately?
The bracket is included. The Tri-Pack ships the arm assembly components together with the P86 bracket, so the arm side of the job is complete out of the box. You still reuse or supply the closer body and its mounting screws for the door and frame.
4) Can I just replace a damaged closer arm instead of the whole door closer?
Yes, that is exactly what the MOD-AO8P is for. It is a purpose-built replacement arm for the 8600 and 7400 Series, so a bent or vandalized arm can be swapped while the closer body stays on the door. For property managers and MRO stock that keeps a door in service with far less labor than a full closer change-out.
5) What finishes does the Dormakaba MOD-AO8P closer arm come in?
Three: 689 aluminum, 693 black, and 695 dark bronze. For a repair, match the number on the closer already on the door so the arm does not stand out against the rest of the openings in the building. 689 is the common default on commercial aluminum storefront and hollow metal work.
6) What does the Round Secure arm designation on the MOD-AO8P mean?
Round Secure refers to the arm's configuration, a round-profile arm with a secured connection at the joint for consistent door control. It is a regular-arm style component of the modular closer system rather than a parallel-arm-only or slide-track assembly, and it pairs with the included P86 bracket.
7) I have several 8600 closers in one building. Can I standardize on one arm part number?
You can, as long as each of those openings uses a non-hold-open regular arm with the P86 bracket. The MOD-AO8P covers both 8600 and 7400 Series closers, so a single line item stocks arms across mixed installs of those two families. Doors that need hold-open have to be ordered as a different arm.
8) Is the MOD-AO8P arm rated for high-traffic commercial doors?
It is a commercial-grade component, specified for office buildings, schools, healthcare, retail, industrial and warehouse facilities, multi-tenant residential and government buildings. It is not a light residential part.
