Dormakaba DOR-T-689-ED900 – Frequently Asked Questions

1) Will the Dormakaba T 689 track arm fit any door closer, or only the ED900 Series?
Only ED900 Series closers. The T 689 ED900 track arm assembly is built to Dormakaba factory specs for the ED900 Series and drops onto an existing ED900 installation with no modification. It is not an arm for other Dormakaba closer families or other brands, so confirm the closer body is stamped ED900 before ordering.
2) What reveal do I need to measure for before ordering the T 689 ED900 arm?
Reveal is a selectable option on the T 689 ED900, so measure the distance from the face of the door to the face of the frame stop before you order. Two reveal choices are offered, 1 inch and 2-3/4 inch. Get this wrong and the arm geometry will not set up correctly, which is the usual cause of a closer that will not control the door through the last few degrees of swing.
3) Can I replace just the arm on my ED900 closer instead of the whole unit?
Yes, that is what the T 689 ED900 is for. It replaces a worn or damaged arm assembly on an existing ED900 installation, so you keep the closer body and extend the service life of the system rather than pulling and re-prepping the door for a complete new closer.
4) What finishes does the Dormakaba ED900 T 689 reveal-mount track arm come in?
Three finish choices: Standard, 693 Black, and 695 Dark Bronze. Standard is paired with the 1 inch reveal option, while 693 Black and 695 Dark Bronze are offered with the 2-3/4 inch reveal. If you are matching other openings in a building that already run dark bronze closer hardware, 695 is the one to specify.
5) What is the difference between a track arm and a standard push-side closer arm on an ED900?
A track arm rides in a slide track rather than working through a jointed forearm and shoe. The T 689 ED900 is the track-style arm, which gives smooth controlled motion through the full swing and a lower profile at the frame, common where a projecting arm is not wanted. If your ED900 was installed with a regular arm and shoe, a track arm is not a straight swap for it, because the track prep at the frame is different.
6) Besides reveal and finish, is there a size option I have to specify on the T 689 ED900?
Yes, there is a separate Size selection alongside reveal and finish. The 1 inch reveal configuration is listed at size 0 inch, and both 2-3/4 inch reveal configurations are listed at size 1 inch. Match the size to the reveal configuration you measured so the arm sets up at the correct geometry.
7) Is the T 689 ED900 arm rated for high-traffic commercial doors?
It is a commercial-duty part, built for high-traffic commercial environments and used on office buildings, schools, healthcare facilities, retail, warehouses, multi-tenant residential and government buildings. It is not sold as a residential item.
8) Is this a genuine Dormakaba part or an aftermarket arm?
Genuine Dormakaba. The T 689 ED900 is manufactured to original factory specifications as an authentic Dormakaba accessory, which matters if you are servicing an ED900 under a maintenance spec that calls for OEM components.
