Dormakaba BP89-689 – Frequently Asked Questions

1) What is the Dorma BP89 backplate used for on an 8900 series closer?
The BP89 is a mounting backplate for Dorma 8900 series door closers in top jamb applications where the frame face is less than 2-7/8 inches. Without enough frame face, the closer body has nothing solid to land on; the plate gives you that surface. It also has a second, upper set of holes that drops the closer down in a top jamb install so it clears a surface applied stop or holder.
2) My door frame face is wider than 2-7/8 inches. Do I still need the BP89 plate?
No. The BP89 exists for top jamb mounting where the frame face measures less than 2-7/8 inches. A frame with more face than that carries the 8900 closer directly, and the plate is unnecessary for that reason alone. The one case where it still earns its place on a wider frame is clearance: the plate's hole pattern lets you drop or shift the closer to get around a stop or holder that is in the way.
3) How much top rail do I need on the door to use a Dorma BP89 backplate?
Minimum top rail width for the BP89 is 1-3/4 inches or 3-1/4 inches depending on the mounting arrangement you choose. Measure the flat rail on the door before ordering. On a narrow top rail aluminum storefront leaf, that number is what decides whether the 8900 mounts at all.
4) Can the BP89 backplate be used on a regular arm (pull side) closer mount, or only top jamb?
Both. Top jamb is the primary use, for frames under 2-7/8 inches of face. On a regular mount the plate is used to clear a mortised stop or holder, which is the usual reason a regular arm 8900 install fights the frame hardware.
5) What finishes does the Dorma BP89 backplate come in?
Three: 689 anodized aluminum, 693 black, and 695 dark duranodic bronze. Order the plate in the same finish as the 8900 closer body it is mounting, since the plate is visible behind the closer on the frame. Those three are the standard aluminum storefront finishes, so matching an existing bank of doors is normally straightforward.
6) Will the BP89 plate fit a Dorma closer from a different series?
The BP89 is specified for the 8900 series. Closer bodies differ in mounting hole pattern between series, so a plate drilled for the 8900 is what you order when the closer on the door is an 8900. Check the model stamped on the closer body before ordering.
7) Is the BP89 backplate rated for commercial door traffic?
Yes, the BP89 is a commercial grade part, sold as a replacement part for Dorma 8900 series closers. It is the plate, not the closer, so it carries no independent operating function of its own.
