Product Description
4040SE-18-AL LCN 4040SE Series Mounting Plate in Aluminum Finish
Drop Plate, Narrow Top Rail or Flush Ceiling, Aluminum (689)
This is a genuine LCN replacement part for the 4040SE Series. Door closers fail in two predictable ways: the closer body itself wears out, or a single sub-component (arm, shoe, cover, mounting plate, cylinder seal) breaks before the rest of the closer is at end of life. Replacing the part instead of the whole closer is the right call when the body is still good - it saves the labor of re-templating a fire-rated door, and it keeps the original Allegion ACN configuration intact so your master key, mounting prep, and arm geometry don't change.

Compliance and Codes
LCN is part of Allegion plc and is a published Buy American Act (BAA) compliant manufacturer for ACN-cataloged components. This part carries the LCN limited warranty when installed on the matching closer body in its original Allegion-cataloged configuration. Verify ANSI/BHMA grade requirements against the parent closer specification before installing on a fire-rated opening.
What's in the Box

Templates and full installation instructions are not included with replacement parts; reference the LCN parent-closer installation document for the 4040SE series for templating and torque specs.
Pro-Installer FAQ
Q: Will this part work on a non-LCN closer?
A: No. LCN 4040SE arms, shoes, covers, and mounting plates are dimensioned and tapped specifically for the LCN 4040SE body. Cross-mounting to a Norton, Dorma, or other manufacturer closer is not supported and is not covered by warranty.
Q: Is the finish factory-applied?
A: Yes. LCN aluminum is a factory finish matched to the parent 4040SE closer family. Field-painted parts will not match other components on the same closer assembly and will not carry the LCN finish warranty.
Q: How do I confirm this is the right part for my closer?
A: Identify the closer body label first - it will read "LCN 4040SE" or similar. The part number on the body must match the 4040SE family. For handed parts, confirm door handing from the inside looking at the hinges. If you are unsure, email sales@lock-depot.com with a photo of the existing closer body and we will confirm fit before you order.
