The Clopay Window Inserts – Medium, Ultra-Grain – Stockton 612 is an OEM decorative snap-in grille designed to refresh or replace the exterior window insert on compatible Clopay residential garage doors. Finished in Clopay’s Ultra-Grain Medium wood-look color to coordinate with Ultra-Grain steel doors, the Stockton 612 pattern delivers a classic rectangular lite layout that upgrades curb appeal while maintaining factory appearance. This insert installs on the exterior side of the window frame and is intended for doors specified by Clopay to use the “Medium” insert format; it’s commonly found on select Classic and Gallery series configurations that accept Decorative Insert Series designs.
Use this replacement when updating a worn insert, changing styles, or matching existing Ultra-Grain finishes across door sections. Installation typically involves removing the current insert and snapping the new insert into the existing Clopay window frame over the glass; always follow the door’s service manual and Clopay parts guidance for your door model and insert designation. Verify compatibility by checking your door’s product label, owner’s manual, or Clopay parts chart for “Medium” insert and “Stockton 612.” For safety, work with the door in the closed and secured position, wear gloves and eye protection, and avoid operating the opener during the procedure.
