Dormakaba MOD SISH 689 – Frequently Asked Questions

1) What exactly is the Dormakaba MOD SISH, the whole closer or just the arm?
It's the arm only. The MOD SISH is a modular door closer arm, an extra heavy-duty spring cushion arm with hold open, sold as a replacement component for compatible Dormakaba closer assemblies. You're not getting a closer body, so the existing closer has to be sound and staying in place.
2) Does the MOD SISH arm hold the door open?
Yes, hold open is built into the arm. The door can be pushed to the open position and stays there until it's pulled back, which is what a receiving door or a corridor opening during deliveries usually needs. On fire-rated openings hold open is generally not permitted unless the device is released by the alarm system, so verify the opening's requirements before specifying a mechanical hold open arm.
3) What does a spring cushion arm actually do on a door closer?
The spring cushion absorbs the shock when the door is thrown open hard, which protects the closer and the frame on abused openings. The MOD SISH uses an extra heavy-duty version of that mechanism, so it suits high-traffic commercial doors, exterior doors catching wind, and back-of-house openings where people shoulder through.
4) What finishes does the Dormakaba MOD SISH closer arm come in?
Three: 689 aluminum, 693 black, and 695 dark bronze. Match the arm to the closer cover already on the door, since a mismatched arm is obvious from the corridor side of the opening.
5) I manage a building with several Dormakaba closers. Can I standardize on the MOD SISH arm?
Only across openings running compatible Dormakaba modular closers. The arm is a modular component intended as a direct-fit replacement within Dormakaba modular closer system configurations, so it swaps cleanly onto those but is not a universal arm for other brands. Confirm the closer body on each door is a supported Dormakaba modular model before buying a batch, and order all of them in one finish to keep the fleet consistent.
6) My closer arm is bent and the door slams. Will replacing just the arm fix it?
If the damage is in the arm, yes, that's exactly what the MOD SISH is for: restoring a compatible Dormakaba closer to its original operating action without pulling the closer body off the door. If the closer itself is leaking oil or the sweep speed no longer responds to the valve adjustment, the problem is in the body and a new arm will not correct it.
7) Is this arm suitable for a house or apartment interior door?
It's built for commercial duty, not residential. The MOD SISH is specified for commercial applications such as office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential common areas, and government buildings. A light residential interior door doesn't need an extra heavy-duty cushion arm.
