LCN Door Closer Drop Plates
11 products
LCN door closer drop plates (also called mounting plates or adapter plates) enable secure installation of LCN closers when standard mounting conditions aren’t met. They’re essential for doors with narrow top rails (less than 3-3/4" to 5-1/2" depending on model), flush ceilings, or glass panels that prevent direct closer mounting. By extending the closer’s mounting position downward, these plates maintain proper arm geometry and closer performance.

LCN door closer drop plates (also called mounting plates or adapter plates) enable secure installation of LCN closers when standard mounting conditions aren’t met. They’re essential for doors with narrow top rails (less than 3-3/4" to 5-1/2" depending on model), flush ceilings, or glass panels that prevent direct closer mounting. By extending the closer’s mounting position downward, these plates maintain proper arm geometry and closer performance.
Key Features
- Model-specific compatibility with LCN 4040XP, 1460, 4010, and other commercial door closer series.
- Narrow top rail solutions: designed for top rails as small as 3-3/4" (4010/4040XP-18) to 4-3/8" (1460-18PA) to 5-1/2" (4040XP-18PA).
- Parallel arm and hinge-side mounting options: some plates (like 18PA series) are optimized for parallel arm configurations.
- Heavy-duty steel or aluminum construction with finishes including aluminum paint (689), dark bronze (695), and black (693).
- Pre-drilled and tapped holes matching LCN closer templates, preventing field re-drilling and ensuring alignment.
- Reinforcement capability: provides additional structural support for hollow metal doors and frames where SDI-100 reinforcing is recommended.
Key Benefits
- Enables proper closer installation on doors that otherwise wouldn’t accommodate standard mounting, expanding closer application flexibility.
- Maintains correct arm geometry for optimal sweep, latch, and backcheck performance, ensuring reliable door control.
- Simplifies retrofit projects by adapting existing door preps to standard closer templates without redrilling.
- Improves structural integrity on glass doors, narrow stiles, and hollow metal doors by distributing closer load across a larger plate area.
- Ensures code compliance by enabling proper installation of hydraulic closers on fire-rated and labeled doors per manufacturer requirements.
Applications
- Hollow metal entrance doors with narrow top rails where direct closer mounting isn’t possible.
- Glass doors and storefronts where glass inserts prevent full-top-rail closer installation.
- Flush ceiling or concealed closer applications where overhead mounting depth is limited.
- Parallel arm installations require precise arm-to-closer alignment on restricted top rail space.
- Institutional, healthcare, and office buildings are standardizing on LCN closers across varied door types.
