Marks USA M9900-M9916 Adapter for 2-1/4" Thick Door, MESC Trim for M9900 Series Panic

The Marks USA M9900-M9916 adapter is designed for use with the M9900 Series panic exit devices when the door thickness exceeds the standard 1-3/4″. This adapter allows the compatible MESC trim to fit doors up to 2-1/4″ thick with the same mounting footprint and functionality. It simplifies installation on thicker doors without modifying the core device or trim setup. The plate features a satin chrome finish (US 32D) to match the architectural hardware, and is engineered to maintain Grade 1 performance standards.

Ideal for retrofits or new installations where high-use exit hardware must be maintained on door thicker than standard, this adapter supports seamless integration, preserves aesthetics and ensures reliable operation in commercial or institutional environments.
