The Clopay Window Inserts – Gray – Stockton 612 is an OEM decorative grille for compatible Clopay residential garage doors that use the Decorative Insert Series window system. Featuring the classic Stockton pattern with clean rectangular panes, this gray insert refreshes the look of your door or replaces a damaged or faded grille while maintaining the original glazing behind it. It is designed to overlay the exterior side of the window, delivering an upgraded multi-pane appearance without altering the door’s operation or the glass itself. Common use cases include replacement on aging doors, aesthetic upgrades to match new exterior finishes, and restoring factory appearance after service.
This replacement part is intended for doors with Clopay’s insert-style window frames and matching Stockton 612 openings, found on many Classic and Gallery steel models. Installation typically involves removing the interior window retainer, swapping the insert, and reinstalling the retainer; ensure the door is fully closed and disconnected from the opener before beginning work. Verify compatibility by confirming your door’s window system and Stockton 612 pattern code, as inserts are pattern- and opening-specific. For longevity, clean with mild soap and water only, and avoid abrasive cleaners. This non-structural insert does not add weight in a way that affects spring balance and requires no electrical setup, making it a straightforward, OEM-fit replacement for Clopay garage door windows.
