Commercial Door Closer Mounting Plate | For Prime 46 Series | Retrofit & Narrow Top Rail Applications

Install a Prime Door Controls 46 Series door closer where standard mounting conditions are limited with the Prime Door Controls 46 Series Drop Plate.

Designed for use with compatible 46 Series surface-mounted commercial door closers, the drop plate provides an alternate mounting surface when the door or frame does not offer enough material for the standard closer mounting pattern.

It is especially useful for retrofit installations, narrow top rails, aluminum storefront doors, and other commercial openings where additional mounting clearance is required.

Why Use a Drop Plate?

A drop plate allows the closer body to be mounted lower on the door or repositioned when the standard mounting holes cannot be used.

Common reasons for using a drop plate include:

• Narrow top rails

• Aluminum storefront doors

• Existing door preparation conflicts

• Limited mounting clearance

• Glass or vision-lite interference

• Retrofit closer installations

• Existing holes that do not match the new closer

• Frame or door construction that prevents standard mounting
