Accentra 3146 689 – Frequently Asked Questions

1) What does the Accentra 3146 drop plate actually do on a door closer install?
The 3146 is a drop plate that lowers the mounting point of an Accentra 3301 or 3501 Series door closer so the closer body can be fastened where the top rail is too narrow to take the closer directly. It also supports 3301/3501 configurations using a concealed door holder. It is a mounting accessory only, not a closer, so you order it alongside the closer body and arm.
2) Will the 3146 drop plate work with a Norton or LCN closer I already have on the door?
No. The 3146 is cut for the Accentra 3301 and 3501 Series closer footprint. Drop plates are series specific, so a plate matched to your existing closer brand and series is what you need instead.
3) My aluminum storefront door has a narrow top rail. Do I need a drop plate to mount a closer?
Yes, that is exactly the case the 3146 covers. On narrow top rail doors there is not enough rail height to land a surface closer body, so the drop plate extends the mounting surface downward. Without it you are field fabricating a bracket. It is intended for commercial openings, including storefront style narrow stile doors.
4) What finishes does the Accentra 3146 drop plate come in?
Six painted finishes: 689 aluminum, 690 dark bronze, 691 light bronze, 693 black, 694 medium bronze and 696 satin brass. If you are matching a run of doors, pick the same number the closers were ordered in so the plate does not read as a patch under the closer body.
5) I am using a 3301 closer with a concealed door holder. Does that change the plate I order?
The 3146 is the plate that handles it. It supports concealed door holder setups within the 3301 and 3501 Series while keeping the hold-open function working, so the same part covers both the narrow top rail problem and the concealed holder arrangement.
6) Is the 3146 drop plate metal, and will it hold up on an exterior entrance?
It is aluminum, which gives corrosion resistance and keeps weight off the door leaf. The plate is built as a commercial-grade accessory for high-traffic openings such as offices, schools, healthcare and municipal buildings.
7) Does the 3146 drop plate change how the closer arm lines up?
The plate is formed to keep proper closer arm geometry and door sweep coverage once the closer is dropped below the top rail. That is the point of using a factory plate rather than shimming or drilling a custom bracket, which throws off arm angle and closing performance.
