Accentra 3148 690 – Frequently Asked Questions

1) What does the Accentra 3148 drop plate actually do on a door closer install?
It lowers the mounting point of the closer body on the frame or door so the closer clears an obstruction overhead. When the head frame or ceiling soffit does not leave enough room to mount the closer in its normal position, the 3148 drop plate relocates it down far enough to mount properly and still let the arm work. It's an installation accessory only, so it does not change the closer's size or spring power.
2) I have an Accentra 4400 closer but the header is too shallow to mount it. Is this the right part?
Yes, order the 3148 in the 4400 series version. That is the drop plate built for the 4400 closer footprint and it moves the mounting location down so a shallow head frame or tight ceiling no longer blocks the install. If your closer is a 3301 or 3501 instead, order that series version.
3) What finishes can I get the 3148 drop plate in to match my existing closers?
Six painted finishes, in both series versions: 689 aluminum, 690 dark bronze, 691 light bronze, 693 black, 694 medium bronze, and 696 satin brass. Those are the standard painted closer finish codes, so matching the plate to the closer body already on the door is a matter of ordering the same number.
4) Do I need a drop plate or a parallel arm bracket for a tight head frame?
They solve different problems. A drop plate like the 3148 lowers the closer body when there is not enough clearance above it, whether that is a narrow head frame face or a low ceiling. A parallel arm bracket changes how the arm attaches so the closer sits on the push side against the frame soffit. If your closer body itself will not fit in the space available, the drop plate is the part you want.
5) Does the Accentra 3148 come with the closer, or is it a separate order?
Separate. The 3148 is a standalone mounting plate ordered on its own, so if you are specifying a new 3301, 3501 or 4400 closer for an opening with clearance problems, add the drop plate in the matching series and finish to the same order. You will also still need the closer's own mounting screws and any arm or bracket option the opening calls for.
6) Can I use one 3148 drop plate for every closer in my building to standardize?
Only where the closers are the same family. The 3148 is made in a 3301/3501 version and a 4400 version, so a mixed fleet needs both. Standardizing is easier if you also settle on one finish code across the property, since all six painted finishes are available in both series versions.
7) Is the 3148 drop plate suitable for high-traffic commercial doors, or is it a light-duty residential part?
It's a commercial part. The 3148 is specified for commercial door hardware use, in offices, schools, healthcare, retail, warehouses, government buildings and multi-tenant residential, and it serves as the structural mounting platform for the closer, so it carries the closer's load rather than just covering holes.
