BEST SDS 689 – Frequently Asked Questions

1) Can I use the SDS arm on a regular arm or top jamb closer installation?
No. The SDS is built for parallel arm mounting, where the arm runs back along the face of the door with the closer body on the pull side stop face. If your existing closer is set up regular arm (closer on the pull side, arm projecting off the frame) or top jamb, this arm is the wrong configuration and you need the arm matched to that mounting.
2) Will the BEST SDS arm fit a non-BEST door closer?
Treat it as a BEST part. The SDS is sold as a replacement arm for compatible BEST door closer systems, and the catalogued feature set ties it to the Dorma door closer parts family (BEST closers share Dorma lineage). Identify the closer body you have before ordering an arm; pinion spline and shoe geometry are what decide fit, and an arm from another manufacturer's closer will not key onto a different pinion.
3) What is the BEST SDS closer arm and what does the Door Saver spring cushion actually do?
The SDS is a complete surface door closer arm assembly for parallel arm mounting, with an integrated Door Saver spring cushion. The cushion takes up closing force near the end of the swing so the impact loads are spread instead of slamming through the door, frame and closer hardware. It ships as a full assembly rather than loose components, so a service call is a swap of the arm rather than a rebuild.
4) I manage a building where doors get flung open into the wall. Is this arm the fix?
A Door Saver spring cushion arm helps, and this is that arm for parallel mount BEST closers. The cushion absorbs force in the closing cycle to protect door, frame and hardware. It is not a substitute for a backcheck valve setting or a floor or wall stop on an opening that gets slammed open hard, so use it alongside those rather than instead of them.
5) Do I get the shoe and bracket, or just the main arm?
It is supplied as a complete arm assembly, so the replacement is one part number rather than an arm plus separate cushion and shoe pieces. Reuse of the existing closer body and its mounting plate is the normal approach; you are replacing the arm linkage, not the closer.
6) What finish does the SDS closer arm come in?
One finish: 689 aluminum painted. That is the standard sprayed aluminum finish used on most commercial closers, so it blends with existing 689 closer bodies on an opening without looking like a patched-in part. If the rest of your closers are a plated or dark bronze finish, the arm will not match.
7) Is the SDS arm rated for commercial traffic or is it a light-duty residential part?
Commercial. The SDS is catalogued as a commercial-grade part and is specified for offices, schools, healthcare, retail, industrial and warehouse space, multi-tenant residential and government buildings, which is the traffic level a surface closer arm on a stairwell or corridor door sees daily.
