Lcn 8310868F 4.5 Inch Round Flush Mount Box

Product Description

The LCN 8310868F is a round flush mount box designed for use with LCN door closer and door hardware installations. The box mounts flush into the door or frame surface, providing a clean, recessed housing that supports proper closer arm positioning and protects the mounting interface in high-traffic applications. At 4.5 inches in nominal diameter, it accommodates the mounting footprint required by compatible LCN closer series. The unit ships as a single piece and weighs 0.6 pounds, making handling and installation straightforward for a single technician.

This flush mount box is suited for commercial and institutional environments where LCN door closers are specified, including schools, hospitals, government buildings, and correctional facilities. It is installed in applications where a recessed mount profile is required, either for aesthetic reasons or to meet clearance requirements on the door or frame. Installation is typically performed by a licensed door hardware technician or commercial contractor as part of a closer rough-in or retrofit.

Compatibility

Designed as an OEM-style accessory for LCN door closer installations requiring a flush mount box configuration. Consult LCN documentation to confirm fitment with your specific closer series before ordering.

Installation Notes

Installation should be performed by a qualified door hardware technician or licensed contractor familiar with commercial door closer systems. Ensure the door or frame is properly supported and all power-operated hardware is de-energized before cutting or drilling for the flush mount box. Follow applicable building codes and the closer manufacturer's rough-in dimensions to position the box correctly before securing it in place. Do not modify the box dimensions or mounting flanges, as doing so may affect closer arm alignment and door operation.
