LCN 4030-18PA 689 – Frequently Asked Questions

1) When do I need the LCN 4030-18PA drop plate instead of mounting the closer directly to the door?
Use the 18PA drop plate on a parallel arm installation when the door's top rail measures less than 5 inches (127 mm) from the stop. On a narrow top rail there isn't enough flat surface to land the closer body, so the plate drops the mounting position down onto the door face. If your top rail is 5 inches or more, you don't need the plate.
2) How much frame clearance does the 4030-18PA drop plate need?
A minimum of 1-3/4 inches (44 mm) clearance is required for the 18PA plate to mount. Measure the available space on the opening before ordering, because below that the parallel arm closer will not fit even with the drop plate.
3) Will the 18PA drop plate work with any LCN closer, or only the 4030?
It is made for the LCN 4030 Series closer. The plate is series-specific because the hole pattern has to line up with that closer's body, so don't plan on using it under a different LCN series.
4) I'm retrofitting an old aluminum storefront and the closer won't sit on the rail. Is this the fix?
That's exactly the case the plate covers. Narrow top rails on existing storefront and renovation work often leave less than 5 inches from the stop, which is too little for the closer body alone. The 18PA plate bridges it as long as you have at least 1-3/4 inches of clearance to work with. It's an installation accessory only, so you still order the 4030 closer separately.
5) Can I use this drop plate for a regular arm or top jamb mount?
No. The 18PA is the parallel arm version, where the closer mounts on the pull side with the arm running back parallel to the door. Regular arm and top jamb installations use different drop plates, so the mounting configuration has to be settled before you pick the plate.
6) What finishes does the LCN 4030-18PA drop plate come in?
Thirteen finishes, so the plate can be matched to the closer and the rest of the openings: 616 satin bronze blackened, 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome, 652 satin chrome, 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. 689 aluminum and 695 dark bronze are the usual choices on commercial aluminum storefront and hollow metal work.
7) Does adding a drop plate affect ADA compliance on the opening?
The 4030-18PA is listed as ADA compliant, so using it to mount a 4030 closer on a narrow top rail does not take the installation out of compliance. That matters on healthcare, education, and government openings where accessible door hardware is required.
8) Does the drop plate come with the closer, or do I order it separately?
It is a separate accessory. The 4030-18PA is the drop plate by itself, one per door, in the finish you choose, and the 4030 closer and its arm are ordered on their own. Standardizing on one plate across a building of narrow rail doors keeps the spare parts simple.
9) Is the 4030-18PA drop plate rated for commercial traffic, or is it a light duty part?
It is a commercial part, built for the same door control duty as the 4030 Series closer it mounts. That's the range it belongs in: offices, schools, healthcare, retail, and multi-tenant buildings rather than residential doors.
