The Clopay Window Inserts – Dark, Ultra-Grain – Stockton 612 is a decorative replacement grille designed to update or restore the look of compatible Clopay residential garage door windows. The Stockton 612 pattern delivers a classic, evenly divided rectangular lite layout that pairs well with traditional and carriage-house door designs. Finished in a Dark Ultra‑Grain color to coordinate with Clopay’s wood‑look steel finishes, this insert helps achieve a cohesive exterior appearance when upgrading existing glass or replacing a damaged grille. It is commonly specified on select Clopay doors that offer the Stockton 612 window option, including models within the Classic and Gallery collections, depending on the door’s panel configuration and window openings.
Engineered as a field‑serviceable component, the insert installs into the existing Clopay window frame system and is typically removable for cleaning or replacement. Installation generally involves accessing the interior window retainer, removing the old grille, and snapping the new insert into place; always follow Clopay’s model‑specific instructions. For best results, confirm door series, panel style (short/long), glass type, and the Stockton 612 layout before ordering to ensure proper fit and color match with the Ultra‑Grain Dark finish. Use mild, non‑abrasive cleaners and soft cloths to maintain appearance, and wear hand protection when working around glass. This non‑electrical component is intended for residential garage door applications and does not include glass or framing hardware.
