Lcn 146018AL Hinge Side Mount Drop Plate 1460 Series

Product Description

The LCN 146018AL is a hinge side mount drop plate designed for use with LCN 1460 Series door closers. It provides a low-profile mounting solution for installations where the top rail measures less than 2.5 inches, or where a top jamb mount is required on a head frame measuring less than 1.75 inches. The plate is finished in 689 aluminum, making it suitable for installations that call for a clean, aluminum-matched appearance. Installation is performed by licensed door hardware technicians or qualified general contractors working with commercial door and frame assemblies.

This drop plate is intended for commercial and institutional door applications including schools, hospitals, government buildings, and similar high-traffic facilities. It is used when standard parallel arm or regular arm closer mounting is not possible due to narrow top rail or head frame dimensions. The 1460 Series closer system is commonly found in heavy-use environments where reliable, code-compliant door closure is required. This plate allows the closer arm assembly to clear the top rail or frame profile and function as intended.

Key Features

• Hinge side mount configuration for top rail installations with less than 2.5 inches of clearance
• Also supports top jamb mount on head frames less than 1.75 inches
• 689 aluminum finish for consistent appearance on aluminum door and frame systems
• Low-profile plate at 0.2 inches height minimizes projection from the door surface
• Sold individually as a single unit replacement or retrofit component

Compatibility

Designed for use with the LCN 1460 Series door closer system in hinge side mount or top jamb mount configurations where top rail or head frame dimensions fall below standard mounting thresholds.

Installation Notes

Installation of this drop plate should be performed by a qualified door hardware technician or commercial door installer familiar with LCN 1460 Series closer assemblies. Verify that the door and frame dimensions match the specified rail and jamb clearance requirements before mounting. Ensure the door closer arm is fully depressurized and the door is secured in an open or safe position before beginning hardware installation. Follow applicable building codes and the closer manufacturer's installation instructions for fastener placement and torque.
