LCN 4040XP-18PA 652 – Frequently Asked Questions

1) Do I need a drop plate for a 4040XP parallel arm install, or can the closer mount straight to the door?
Measure from the stop down across the top rail. Parallel arm mounting of a 4040XP wants 5-1/2 inches (140mm) of top rail from the stop for the closer body to land on. Anything less than that is what the 4040XP-18PA drop plate exists for: it gives the closer a mounting surface on a short rail, down to a 2 inch (51mm) minimum rail. If you have the full 5-1/2 inches, you do not need the plate.
2) My aluminum storefront door has about a 2 inch top rail. Will the LCN 4040XP-18PA work on it?
Two inches is the floor. The 4040XP-18PA parallel arm drop plate needs a minimum 2 inch (51mm) top rail to fasten to, and it is meant for rails measuring less than 5-1/2 inches (140mm) from the stop. At exactly 2 inches you are at the limit and it will mount. Under 2 inches there is not enough rail to carry the plate, and that opening needs a different mounting method for the closer.
3) Is the 4040XP-18PA the right drop plate for a regular arm or top jamb mounted closer?
No. The PA stands for parallel arm, and this plate is cut for the 4040XP mounted push side with the arm running back parallel to the door face. Regular arm (pull side) and top jamb installs take LCN's standard 4040XP-18 drop plate instead. The two are not interchangeable, so pin down the mounting side before you order.
4) What is a door closer drop plate and why would I need one?
A drop plate is a flat mounting plate that goes between the closer body and the door, giving you a fastening surface when the rail itself is too short to take the closer. Nothing about the closer's operation changes; it just relocates where the body sits. The 4040XP-18PA is the parallel arm version for the LCN 4040XP, and it covers rails under 5-1/2 inches (140mm) from the stop, with 2 inches (51mm) of rail as the least it can work with.
5) What finishes does the LCN 4040XP-18PA drop plate come in, and does it have to match the closer?
Fourteen finishes: 616 Satin Bronze Blackened, 622 Matte Black, 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. The plate sits under the closer body in plain view, so order it in the same finish code as the closer. 689 Aluminum is LCN's standard painted finish and is what most commercial openings end up with.
6) I'm replacing closers on a set of doors with short top rails. What do I order besides the closers?
One 4040XP-18PA per closer, matched in finish. The plate is a per-leaf item, so a pair of doors with a closer on each leaf takes two. Order it any time the parallel arm install has less than 5-1/2 inches (140mm) of top rail below the stop, and confirm each rail is at least 2 inches (51mm) before you commit the whole run. Openings on the same building that already have the rail depth take the closer with no plate at all.
7) Can the 4040XP-18PA be used on an ADA accessible opening in a commercial building?
Yes. LCN specifies the 4040XP-18PA as ADA compliant, and it is a commercial-duty part. Worth knowing for the inspection: the plate only changes where the closer body mounts, while the opening force an ADA opening has to meet is set at the closer itself through spring size and valve adjustment.
