LCN 4040XP-18 Drop Plate for Regular Arm Door Closer Installation

The LCN 4040XP-18 Drop Plate solves a specific field problem: when a door's top rail is too narrow for a standard regular-arm closer mount. If the top rail measures less than 3-3/4" (95 mm) — but at least 2" (51 mm) — this drop plate repositions the closer to achieve proper geometry and full arm travel. Without it, the closer either can't be mounted or will bind. It is designed for hinge-side regular-arm installations on LCN 4000 Series door closers, including the 4040XP.

Key Features

  • Narrow Top Rail Solution: Required when top rail is under 3-3/4" (95 mm); minimum 2" (51 mm) clearance needed.
  • 4000 Series Compatible: Engineered for LCN 4040XP and compatible 4000 Series door closer models.
  • Regular Arm / Hinge-Side Mount: Enables correct closer positioning in hinge-side regular-arm configurations where standard mounting is not feasible.
  • Commercial-Grade Construction: Built to commercial standards for long-term reliability in high-cycle door applications.
  • ADA Compliant: Supports ADA-compliant door closer installations in commercial environments.
  • Available in 7 Finishes: Match existing hardware with options including 689 Aluminum, 693 Gloss Black, 695 Dark Bronze, 690 Statuary Bronze, 691 Light Bronze, 696 Brass, and 632 Bright Brass.

Technical Specifications

  • Top Rail Requirement: Less than 3-3/4" (95 mm)
  • Minimum Top Rail Clearance: 2" (51 mm)
  • Compatible Closer Series: LCN 4000 Series (4040XP)
  • Mount Type: Regular Arm, Hinge Side

LCN 4040XP-18-695 – Frequently Asked Questions

1) How do I know if my door needs the LCN 4040XP-18 drop plate?
Measure the top rail. The 4040XP-18 is the plate you add when that rail measures less than 3-3/4 inches (95 mm), which is not enough room to land a 4000 Series closer in the normal regular arm position. The plate repositions the closer body lower on the door so the arm still gets full travel. There is a floor to it as well: you need at least 2 inches (51 mm) of top rail for the plate itself to mount. So the working window is 2 inches up to just under 3-3/4 inches. At 3-3/4 inches or wider, you don't need the plate at all, and the closer mounts straight to the rail.
2) My aluminum storefront doors have about a 3 inch top rail. Can I just mount an LCN 4040XP closer as is and skip the drop plate?
At 3 inches you are inside the range where the drop plate is required. The cutoff is 3-3/4 inches (95 mm): anything narrower than that doesn't leave enough rail to position a regular arm 4000 Series closer correctly, and the 4040XP-18 plate is what solves it. Three inches also clears the plate's own 2 inch (51 mm) minimum, so the plate will mount. Order the plate with the closer rather than trying to make the standard mount work.
3) Can the LCN 4040XP-18 drop plate be used on a parallel arm closer installation?
It can't. The 4040XP-18 is made for regular arm, hinge side mounting, the pull side arrangement where the closer body sits on the door and the arm reaches across to the frame face. Parallel arm and top jamb installations use their own plates and brackets with different hole patterns. If your 4040XP is going on parallel arm because of a narrow rail or a stop condition, the -18 plate is the wrong part for that opening.
4) Will the 4040XP-18 drop plate work with other LCN 4000 Series closers, or only the 4040XP?
The plate is built for the LCN 4040XP and compatible 4000 Series closers, so it is not a 4040XP-only part. What it will not do is cross series. If the closer on the door is from another LCN family, or another manufacturer entirely, this is not the plate for it. Confirm the closer body is a 4000 Series before ordering.
5) Does the LCN 4040XP-18 come with the door closer, or am I buying just the plate?
Plate only. The 4040XP-18 is a replacement part for 4000 Series door closers, so the closer body, the arm and any other trim are separate line items on the order. If you're doing a pair of doors, each leaf carries its own closer and its own drop plate, so that's two plates, not one.
6) Does adding a drop plate under the closer affect ADA compliance on the opening?
The 4040XP-18 is ADA compliant, so putting it under a 4000 Series regular arm closer does not take a compliant installation out of compliance. It changes where the closer body sits on the door, not how the closer is set. Opening force, closing speed and latch speed are still adjusted at the closer itself, and those adjustments are what a facility inspection actually looks at.
7) What finishes does the LCN 4040XP-18 drop plate come in so it matches the closers already on my other doors?
Seven finishes: 632 bright brass, 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze and 696 brass. These are the standard closer finish codes, so the simplest approach across a building is to read the code off an existing 4000 Series closer and order the plate in the same number. The plate sits in plain view under the closer body on the pull side of the door, so a mismatch shows.
8) Is the LCN 4040XP-18 drop plate a commercial part, or would it suit a residential door?
Commercial. The 4040XP-18 is catalogued for commercial door control work, which is where you find 4000 Series closers on high traffic openings in offices, schools, healthcare, retail and multi-family common areas. A residential entry door rarely has the narrow top rail condition this plate exists to solve.
