Dormakaba BP86-689 – Frequently Asked Questions
1) What is the Dormakaba BP86 backplate used for on a door closer install?
The BP86 is a mounting backplate for Dormakaba 8600 and 7000 Series door closers. It solves two install problems: top jamb mount when the overhead ceiling clearance is under 2-1/4 inches (57 mm), and regular (hinge side) mount where the closer body has to clear a mortised stop/holder in the frame. If neither of those conditions applies to your opening, you do not need it.
2) I only have about 2 inches of head clearance above the frame for a top jamb closer. Will the BP86 let me mount it?
That is exactly the case it is made for. Dormakaba calls for the BP86 backplate on top jamb mount of 8600 Series closers when overhead ceiling clearance is less than 2-1/4 inches (57 mm). The plate repositions the closer so the shoe and cover clear the soffit.
3) Will the BP86 plate work with a 7000 Series Dormakaba closer, or is it 8600 only?
It covers both. The BP86 is listed for use with Dormakaba 8600 and 7000 Series closers. The specific clearance condition Dormakaba documents (less than 2-1/4 inch, or 57 mm, overhead clearance on top jamb mount) is called out for the 8600 Series.
4) My frame has a mortised stop and holder and the closer body hits it. Is there a Dormakaba plate that fixes that?
Yes, the BP86 backplate. Besides the low-headroom top jamb application, Dormakaba specifies it for regular mount to clear a mortised stop/holder, which shifts the closer off the frame face enough for the body to miss the stop.
5) What finishes does the Dormakaba BP86 closer backplate come in, and can I match my existing closer cover?
Three finishes: 689 anodized aluminum (painted aluminum), 693 black, and 695 dark duranodic bronze. Those are the standard Dormakaba closer cover finishes, so order the plate in the same number as the closer already on the opening and it will read as one assembly.
6) Does the BP86 backplate come with the closer itself or the arm?
No. The BP86 is the backplate only, ordered by finish. The closer body, arm, and cover are separate, so you need a Dormakaba 8600 or 7000 Series closer already on hand or on the same order.
7) Is the BP86 backplate a repair part, or something I order with a new closer?
Both work. Dormakaba catalogs the BP86 as a replacement part, so it can be bought on its own to correct an existing 8600 or 7000 Series installation, and it is also the accessory you add to a new closer order when you already know the opening has low headroom or a mortised stop in the way.
8) Is the BP86 rated for commercial openings or is it a residential-grade part?
Commercial. The BP86 is a commercial door hardware part, matched to the Dormakaba 8600 and 7000 Series closers used on institutional and multi-family openings rather than a residential closer line.
