LCN 4030-18TJ 689 – Frequently Asked Questions

1) When do I need the LCN 4030-18TJ drop plate instead of mounting the closer directly to the frame?
You need the 18TJ drop plate on a top jamb installation when the head frame face is less than 2-1/4 inches (57 mm), or when the door sits under a flush ceiling and there is no room to mount the closer body directly. The plate drops the closer down far enough to get a solid mounting surface. It needs at least 1-1/2 inches (38 mm) of clearance to install.
2) Will the 18TJ drop plate work with LCN closers other than the 4030 Series?
The 18TJ plate is made for LCN 4030 Series closers and is drilled for that body. Other LCN series use their own drop plates, so don't plan on this one under a different family closer.
3) I only have about 1-1/2 inches of clearance above the door. Is that enough for the LCN 18TJ drop plate?
That is the floor, not a comfortable margin. The 18TJ drop plate calls for 1-1/2 inches (38 mm) minimum clearance. Measure from the finished condition, not the rough opening. Anything under that and top jamb mounting with this plate is off the table; you'd be looking at a different mounting position for the closer.
4) What finishes does the LCN 4030-18TJ drop plate come in so it matches my closer covers?
Thirteen finishes: 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. Order the plate in the same finish code as the closer cover already on your other openings and it will read as one assembly.
5) Does adding a drop plate to a top jamb closer install cause a problem with ADA accessibility requirements?
No. The 4030-18TJ is an ADA compliant accessory, so using it to gain a mounting surface does not take the opening out of compliance. It is a commercial-rated part, which is what an institutional or government spec will be looking for.
6) Is the LCN 18TJ drop plate a door closer, or do I order the closer separately?
It is a mounting plate only, not a closer. The 18TJ is an installation accessory that goes between the frame or soffit and a 4030 Series closer body. You order the closer, arm and any cover separately.
7) My building has a narrow head frame on a run of doors. Can I standardize on this one plate across all of them?
Yes, if they are all 4030 Series closers mounted top jamb and the frames measure under 2-1/4 inches. That is exactly the condition this plate exists for, and it is sold in a single finish-selectable part, so a property manager or MRO buyer can stock one line item and one finish code across the run.
