Accentra (Yale) 3158 Exposed-Back/Narrow Top Rail Drop Plate

The Accentra (Yale) 3158 Drop Plate is a mounting accessory designed to adapt the installation of 3000 Series door closers on doors with exposed-back or narrow top rail configurations. When a door's top rail lacks sufficient mounting surface, this drop plate provides the additional space needed to properly position and secure the closer body. Built to pair with the Accentra 3000 Series closers, it ensures a clean, reliable installation where standard mounting isn't possible. Manufactured to commercial standards, the 3158 is a practical solution for retrofit and new installations alike, giving installers the flexibility to handle a wide range of door frame conditions.

Features

• Designed specifically for exposed-back and narrow top rail door applications.
• Provides additional mounting surface where the top rail is insufficient for a standard closer installation.
• Compatible with Accentra (Yale) 3000 Series door closers.
• Durable construction suited for commercial door environments.
• Straightforward retrofit and new-installation solution.

Functional Details

The drop plate mounts to the door or frame and lowers the closer position, allowing the closer body to be installed on doors that do not provide adequate top rail space for conventional mounting.
