The Clopay Window Inserts–Slate, Ultra-Grain–Grille on Arch1 is an OEM replacement/upgrade grille designed for Clopay garage doors that feature Arch1 window openings. It delivers the classic arched, divided‑light appearance and is finished to coordinate with Clopay’s Ultra‑Grain Slate wood‑look color, helping homeowners maintain consistent curb appeal when refreshing damaged or outdated window trim. In Clopay’s nomenclature, “Grille on” indicates exterior-applied grilles (not grilles between the glass), making this insert ideal for residential doors originally ordered with the exterior grille style.
This insert is intended for compatible Clopay steel door series that use the Arch1 window frame and Ultra‑Grain Slate finish—commonly seen on models such as Gallery Steel and Bridgeport Steel when configured with “Grille on” windows. It is not interchangeable with GBG (grilles‑between‑glass) window configurations. Installation typically involves removing the existing exterior grille and securing the new insert to the factory window frame per Clopay instructions; work with the door in the fully down position and avoid any contact with counterbalance hardware. For an exact match, verify your door’s model, color/finish, and window layout code (Arch1) on the original order or product label, or consult a Clopay dealer or the official Clopay door and window option charts.
