Top Jamb Application

In a top-jamb installation, the closer body is mounted to the frame head above the door, typically on the push side of the opening.

This mounting method is commonly used where mounting the closer body directly to the door is impractical or where the door and frame configuration favors a frame-mounted closer.

Why Use a Top Jamb Drop Plate?

A drop plate provides additional mounting flexibility when the available frame face is too narrow or otherwise unsuitable for direct closer installation.

Common applications include:

• Narrow frame heads

• Limited frame-face mounting space

• Aluminum storefront frames

• Existing closer mounting holes

• Hardware interference

• Retrofit closer installations

• Replacement closer applications

• Architectural frame configurations
