Commercial Door Closer Mounting Plate | Push-Side Parallel Arm Application | For Prime 46 Series Closers

Expand installation options for the Prime Door Controls 46 Series commercial door closer with the 46 Series Parallel Arm Drop Plate.

Designed for compatible parallel-arm closer installations, this mounting plate provides an alternate mounting surface when the door's top rail does not provide enough room to mount the closer body directly.

It is especially useful for aluminum storefront doors, narrow top rails, retrofit applications, and other commercial openings requiring a push-side parallel arm installation.

Key Features

• Designed for Prime Door Controls 46 Series door closers

• Parallel arm drop plate

• Intended for push-side closer applications

• Provides an alternate mounting surface for the closer body

• Ideal for doors with narrow top rails

• Useful for aluminum storefront applications

• Helps accommodate limited mounting clearance

• Excellent for retrofit and replacement installations

• Commercial-grade closer accessory

• Designed for commercial and institutional openings

• Suitable for professional door-service applications

Parallel Arm Application

In a parallel-arm installation, the closer body is mounted on the push side of the door, with the arm positioned approximately parallel to the door when the opening is closed.

Parallel-arm mounting is commonly used on commercial openings because it provides:

• A cleaner push-side appearance

• Reduced arm projection

• Better protection from pedestrian traffic

• Compatibility with many exterior commercial openings

• Improved installation flexibility

Why Use a Drop Plate?

A drop plate is useful when there is not enough mounting surface on the door for the closer body.

Common conditions include:

• Narrow aluminum top rails

• Storefront doors

• Existing hardware conflicts

• Previous closer preparations

• Vision-lite interference

• Limited mounting clearance

• Retrofit closer installations

The plate provides a larger mounting surface while allowing the Prime 46 Series closer to remain in the required parallel-arm position.

Designed for the Prime 46 Series

The Prime Door Controls 46 Series is a heavy-duty ANSI Grade 1 commercial surface closer with adjustable spring power from Size 1–6.

This parallel-arm drop plate is intended as a mounting accessory for compatible 46 Series installations.
