Sargent 82-3088 Inside Plate & Adaptor Mounting Assembly

The Sargent 82-3088 is a critical architectural mounting component designed for Sargent 7800 and 8200 Series Mortise Locks. This assembly acts as the internal structural bridge, ensuring your lever trim remains perfectly centered and securely attached to the door. Engineered for professional-grade durability, the 82-3088 is essential for maintaining the "wobble-free" operation of Sargent’s most popular architectural rose and escutcheon designs.

Precision Compatibility & Design Features

• Versatile Trim Support: Specifically engineered for use with Sargent’s signature rose designs, including "LN" (Large), "O" (Standard), and "E" (Small) profiles.
  
• Escutcheon Ready: Fully compatible with "LW1" Escutcheon trim, providing the necessary alignment for high-traffic commercial lever sets.
  
• Robust Mechanical Foundation: The adaptor assembly provides the threaded interface required to accept thru bolts, creating a high-strength "sandwich" grip through the door and lock body.
• Direct OEM Replacement: Manufactured by Sargent to original factory specifications, ensuring perfect timing and fit with the internal hubs of 8200 and 7800 series mortise cases.
• Institutional Grade Reliability: Built to withstand the constant torque and leverage applied to levers in schools, hospitals, and busy office environments.

The Sargent 82-3088 is the solution for a lever or rose that has become loose or detached from the door. Often, the internal threads of the original adaptor can become stripped over decades of use. Because this assembly utilizes high-strength thru bolts to anchor the exterior trim to the interior plate, replacing a worn 82-3088 instantly restores the structural integrity of the entire lockset.

Installation Note: When installing the adaptor, ensure it is oriented correctly with the lock body hubs before tightening your mounting screws. This ensures the lever spindle can pass through freely without binding. For high-vibration environments, we recommend a small amount of thread-locker on the mounting screws to prevent future loosening.
