Dormakaba MOD SIS 693 – Frequently Asked Questions

1) What is the Dormakaba MOD SIS arm and what does the spring cushion do?
The MOD SIS is a modular door closer arm for Dormakaba closers, built with an extra heavy-duty spring cushion. The cushion arm absorbs the swing when a door is thrown open hard, so the closer and the door edge take the abuse instead of the frame or the wall. It is the arm you want on entries that get kicked open or catch wind, not a standard regular-arm application.
2) Is the MOD SIS a complete door closer or just the arm?
Arm only. The MOD SIS is a replacement arm assembly that mounts to a compatible Dormakaba closer body, so you will need the closer itself already on the door. Order it when the existing arm is bent, worn, or you are upgrading a standard arm to a cushion arm.
3) Will the MOD SIS arm fit a non-Dormakaba closer like an LCN or Norton?
No. It is a genuine Dormakaba (Dorma) component made to fit compatible Dormakaba closer bodies. Arm spindle broaches and shoe geometry differ by manufacturer, so it should not be used to repair an LCN, Norton, or other brand closer. Match the arm to a Dormakaba closer.
4) What finishes does the Dormakaba MOD SIS closer arm come in?
Three: 689 aluminum, 693 black, and 695 dark bronze. Those are the standard BHMA painted finish codes, so a 689 arm will sit correctly next to 689 closer covers and 689 exit hardware already on the building. If you are matching a fleet of openings, pick the code that is already on your closer covers rather than eyeballing the color.
5) Is this arm rated for high-traffic commercial doors or is it a light-duty part?
Commercial duty. The MOD SIS is specified for commercial use, not residential, and the extra heavy-duty cushion is aimed at high-traffic openings: offices, schools, hospitals, retail, warehouses, multi-tenant residential, and municipal buildings.
6) Why choose a spring cushion arm instead of a standard or hold-open closer arm?
A cushion arm exists to stop overswing. When the door opens past the closer's designed range, the cushion takes the shock, which protects the closer arm, the hinges, and the wall behind the door. A regular arm gives you none of that, and a hold-open arm keeps the door parked open but does nothing about abuse. On exterior doors, high-wind openings, and corridors where carts go through, the cushion arm is the one to spec.
7) Can I swap the arm without pulling the whole door closer off the door?
Yes, that is the point of the modular design. The arm comes off the closer spindle and the shoe comes off the frame bracket, so a worn or bent arm can be changed with the closer body left mounted. Keeps an opening out of service for minutes rather than a full closer replacement.
