Corbin Russwin 188F65 689 – Frequently Asked Questions

1) When do I actually need a drop plate like the Corbin Russwin 188F65?
You need one when the door's top rail is too narrow to mount the closer the regular way. The 188F65 drops the mounting surface down so a DC3220 with full cover can still be installed parallel arm or top jamb. If your top rail is wide enough to take the closer shoe directly, skip the plate.
2) Can I use the 188F65 plate on a fire-rated door?
Yes for the closer assembly it belongs to, which is UL10C positive pressure listed up to 3 hours and UL-cUL listed. One caution: the hold open arm option is not for fire doors, so on a rated opening order the closer without hold open.
3) What finishes does the Corbin Russwin 188F65 drop plate come in?
Six: 600 primed for painting, 689 anodized aluminum, 690 dark bronze, 691 light bronze, 693 black, and 696 satin brass. Pick the one matching the closer cover so the plate does not stand out under the closer. If you are painting to match a custom door color, order 600.
4) Is the drop plate handed? I have doors swinging both ways in the same building.
The closer setup it serves is non-handed, with a single model supporting up to four mounting positions, so you are not ordering left and right versions. One part number covers your openings regardless of swing.
5) Is this an ANSI Grade 1 assembly, and is it ADA compliant?
The closer this drop plate supports is certified to ANSI/BHMA A156.4 Grade 1 and meets ADA/ANSI A117.1. It is also TAA compliant, which matters if you are buying on a government or federally funded contract.
6) How heavy a door will this closer setup handle, and how wide?
Spring power adjusts from size 1 through 6, covering doors up to 250 lbs. Recommended maximum interior door width is 54 inches. Opening range is 140 degrees pull side and 110 degrees push side, so check clearance on the push side before committing to a parallel arm mount with the drop plate.
7) What is the difference between the Corbin Russwin 188F65 drop plate and the Design Hardware 116 parallel arm drop plate?
Both are non-handed parallel arm drop plates that let a closer mount where the top rail is too narrow for regular installation. The 188F65 is a Corbin Russwin replacement part for the DC3220 full cover closer and comes in six finishes, including 689 anodized aluminum, 690 dark bronze and 600 primed for painting. The Design Hardware 116 Parallel Arm Drop Plate is a steel plate 3-1/2 inches in height, rated standard duty, and belongs to the 116 Series closer line.
8) I need a taller drop plate than 3-1/2 inches for a narrow top rail - what options are there?
Among Design Hardware plates, the 316-PA-DP and the 416-PA-DP are both 5 inch parallel arm drop plates, versus 3-1/2 inches on the 116 plate. Note that each of those is tied to its own closer series - 316 Series and 416 Series respectively - so the plate height only helps if you are installing the matching closer. The Corbin Russwin 188F65 serves the same narrow-top-rail purpose for the DC3220 full cover closer.
9) Will a friction hold open arm do the same job as the 188F65 drop plate?
No - they solve different problems. The 188F65 is a mounting plate that permits parallel arm or top jamb mounting when the door top rail is too narrow to take the closer in the regular manner. The Design Hardware 316/116 Friction Hold Open Arm is a closer arm for the 116/316 Series that holds the door open; it does nothing to address a narrow top rail. If you need both hold open and a narrow rail solution on a Corbin Russwin DC3220, the drop plate and the hold open arm are separate line items.
10) Does the drop plate give me any adjustment room once it is up?
There is 1/2 inch of vertical adjustment in the mounting, which is usually enough to clear a stop or line the arm up when the rail geometry is tight. Beyond that you are into relocating the plate itself.
11) Can I add hold open to a door where I am using this drop plate?
Hold open is available on the arm, not the plate. Specify DC5200 x A1 for the hold open arm. Do not use it on a fire rated opening.
