Corbin Russwin 188F63-8-689 – Frequently Asked Questions

1) What is the Corbin Russwin 188F63 bracket actually for?
The 188F63 is a parallel arm flush transom bracket for DC3000 and DC6000 Series door closers. You need it when you're mounting the closer parallel arm on a door with a flush transom, or when the top rail is too narrow to take the closer the regular way. It lets you do parallel arm or top jamb mounting in those situations. It's the mounting bracket only, not the closer itself.
2) Do I get the door closer with the 188F63, or just the bracket?
Just the bracket. The 188F63 is a replacement/accessory mounting part, and the DC3000 or DC6000 Series closer it mounts has to be ordered separately. If your top rail is narrow or you have a flush transom, plan on the closer, the bracket, and the correct arm for the mounting side.
3) My transom panel sits flush with the frame face - can I still parallel arm mount a closer there?
Yes, that's the exact case the 188F63 solves. On a flush transom there's no soffit for the parallel arm shoe to land on, so the bracket gives the arm a mounting surface. Without it you'd be forced to a different mounting method or a transom-mounted closer.
4) Can I use this bracket setup on a fire rated door?
The closer arrangement is UL10C positive pressure rated up to 3 hours and UL-cUL listed, so the standard parallel arm installation is fine on rated openings. What you cannot do on a fire door is the hold open arm - hold open (A1) is not for fire doors. Use a standard arm there.
5) Is the 188F63 handed - do I need a left or right version?
No handing to specify. The DC series closers this bracket serves are non-handed, with a single model supporting up to four mounting positions, so you order the 188F63 by finish only.
6) What finishes does the 188F63 transom bracket come in?
Five: 689 anodized aluminum, 690 dark bronze, 691 light bronze, 693 black, and 696 satin brass. Pick the one that matches the closer body and cover already on the opening so the bracket doesn't stand out at the head.
7) How heavy and how wide a door will this parallel arm closer setup handle?
Spring power adjusts through sizes 1 to 6, covering doors up to 250 lbs, with a recommended maximum interior door width of 54 inches. Standard door thickness is 1-3/4 inches. On the pull side you get up to 140 degrees of opening, 110 degrees push side, so check your wall or adjacent obstruction before committing to a mounting side.
8) Does using this bracket affect ADA compliance or the Grade 1 rating?
No. The DC series closers it mounts are certified to ANSI/BHMA A156.4 Grade 1 and comply with ADA/ANSI A117.1, and they're TAA compliant for government work. Parallel arm mounting with the transom bracket is a standard listed application.
9) I need some vertical wiggle room at the head - how much adjustment is there?
1/2 inch of vertical adjustment is built in, which is usually enough to clear an uneven transom joint or line the arm up with an existing closer footprint. Closing and latching speed valves face forward for adjustment after the bracket is up, and backcheck is standard.
10) Is the 188F63 suitable for residential use or is it a commercial-only part?
It's a commercial door control part. Typical use is office buildings, schools, healthcare, retail, warehouses, multi-tenant residential common doors, and government buildings - openings where a Grade 1 closer is already specified.
