Top Jamb Application

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

Top-jamb mounting is commonly used where mounting the closer directly to the door is impractical or where the opening configuration favors frame-mounted installation.

Typical applications include:

• Commercial exterior doors

• Aluminum storefront entrances

• Hollow metal frames

• Narrow top-rail doors

• High-traffic commercial openings

Why Use a Top Jamb Drop Plate?

A drop plate helps provide the mounting surface needed when the existing frame face is too narrow or otherwise unsuitable for direct closer installation.

Common conditions include:

• Narrow frame heads

• Limited mounting surface

• Aluminum storefront framing

• Existing closer mounting holes

• Hardware interference

• Retrofit installations

• Replacement closer applications

• Architectural frame conditions
