Dormakaba MOD SDS 689 – Frequently Asked Questions

1) What does the door saver spring cushion on the Dormakaba MOD SDS arm actually do?
The spring cushion on the MOD SDS arm takes the shock at the end of the opening swing. Instead of the door slamming into a wall or racking the closer body and frame when someone throws it open, the extra heavy-duty cushion absorbs that force and controls the last part of the arc. On a high traffic opening, that is what keeps the closer, the door, and the frame from wearing out early.
2) Is the MOD SDS a parallel arm or a regular arm closer arm?
Parallel arm. The MOD SDS is built in a parallel arm layout, so it suits openings where the closer body mounts on the push side and the arm runs back along the face of the door under a soffit-mounted shoe. If your existing closer is set up as a regular (pull side) arm, this is not the arm for that installation.
3) Will the Dormakaba MOD SDS arm fit my existing closer?
The MOD SDS is a modular replacement arm for compatible Dormakaba (Dorma) door closer systems. It is sold as a replacement part within that closer arm ecosystem, so it goes on a Dormakaba closer body, not on another manufacturer's closer. Match it to the Dormakaba closer series already on the door before ordering.
4) What finishes does the Dormakaba MOD SDS closer arm come in?
Three: 689 aluminum, 693 black, and 695 dark bronze. Those are the standard BHMA numbers, so if the closer cover and hinges on your other openings are already 689 or 695, the arm will match the rest of the building without a paint step.
5) Do I need a spring cushion arm or will a standard parallel arm do?
Use a cushion arm like the MOD SDS where the door gets opened hard and there is nothing to stop it: stairwells, service corridors, loading areas, school and hospital traffic. It builds a stop into the arm itself. If the opening already has a wall stop or floor stop and normal traffic, a plain parallel arm is enough. The MOD SDS is the extra heavy-duty version of the cushion arm, so it is aimed at the abusive openings rather than an office door.
6) Can I add the MOD SDS arm to a closer I already have installed instead of replacing the whole closer?
That is the point of the modular design. The MOD SDS swaps onto a compatible Dormakaba closer body, so if the arm is bent or the old one has no cushion, you change the arm and keep the closer, the shoe location, and the existing prep. No full system replacement.
7) Is the MOD SDS arm suitable for a residential door?
It is a commercial part. The MOD SDS is specified for commercial use, in offices, schools, healthcare, retail, industrial buildings, multi-tenant residential, and government facilities. On a single-family interior door it is more arm than the opening needs.
