LCN 4040XP-18TJ-652 – Frequently Asked Questions

1) What is the LCN 4040XP-18TJ drop plate actually for?
It's a mounting plate for a top jamb mounted LCN 4000 Series door closer. When the face of the head frame is less than 3-1/2 inches (89 mm), there isn't enough flat surface to land the closer body squarely, so the plate drops below the frame face and centers the closer vertically. You still need a head frame of at least 1-3/4 inches (44 mm) for it to mount. The closer itself is a separate order; the 18TJ is the bracket only.
2) My head frame face is 2 inches. Do I need a drop plate for a top jamb closer?
Yes. Anything under a 3-1/2 inch (89 mm) frame face is exactly the condition the 18TJ plate is made for, and a 2 inch frame clears the 1-3/4 inch (44 mm) minimum, so it will mount. Frames at or above 3-1/2 inches usually take the closer directly on the frame face with no plate.
3) Is the LCN 18TJ drop plate for top jamb or parallel arm mounting?
Top jamb. It mounts on the frame face above the door with the closer pushing from the stop side. Parallel arm installs, where the closer body sits on the door under the frame soffit, use a different drop plate, so match the plate to the mounting style called out on your door schedule before ordering.
4) What finishes does the LCN 4040XP drop plate come in?
Twelve finishes, so you can match whatever is already on the closer: 689 Aluminum and 693 Gloss Black for painted frames, 690 Statuary Bronze, 691 Light Bronze, 695 Dark Bronze and 639 Satin Bronze in the bronze range, 616 Satin Bronze Blackened, 651 Bright Chrome and 652 Satin Chrome, and 632 Bright Brass, 633 Satin Brass and 696 Brass. Order the plate in the same finish code as the closer body, since the two sit next to each other on the frame.
5) Can I standardize one drop plate across a building with mixed frame depths?
Only for the openings with narrow head frames. The 18TJ plate applies where the frame face is under 3-1/2 inches (89 mm) and at least 1-3/4 inches (44 mm) deep. Openings with a full 3-1/2 inch or wider frame face take the closer straight onto the frame with no plate, so a fleet order should be counted off a frame survey rather than a flat count of doors.
6) Is the LCN 4040XP drop plate ADA compliant for a school or hospital door?
The 4040XP drop plate is listed as ADA compliant and is a commercial-grade part, used on office buildings, schools, healthcare, retail, industrial, multi-tenant residential and government work. Worth remembering that ADA compliance on the opening comes down to the closer's opening force and closing speed adjustment, not the bracket, so specify the closer accordingly.
7) Is this a replacement part I can order to fix an existing closer install?
Yes, the 18TJ is stocked as a replacement part for LCN 4000 Series door closer installations. If an existing top jamb closer is sitting off-center or was shimmed onto a narrow frame, the drop plate is the correct fix, and it swaps without changing the closer body.
