The Clopay Window Inserts—Slate, Ultra‑Grain, Vertical Grille on Arch1—are decorative grille inserts for select Clopay residential garage doors that feature the Arch1 window layout. The Vertical Grille on Arch1 pattern adds upright mullions over a graceful arch, creating a classic carriage‑house look while letting natural light into the garage. Finished in Ultra‑Grain Slate, the insert coordinates with Clopay’s wood‑look steel finishes for a cohesive, factory‑matched appearance on doors finished in Ultra‑Grain Slate. It can be specified on new doors or ordered as a replacement insert for compatible Clopay models that accept Arch1 windows.
Compatibility varies by door series and region, but this style is commonly offered on Clopay’s carriage‑house inspired steel lines such as Gallery, Bridgeport Steel, and Coachman that support Arch1 designs and Ultra‑Grain finishes. Depending on the door model, it can be paired with various glazing options (e.g., clear, frosted, obscure, rain, seeded, or tinted), and in areas that require it, with WindCode/impact‑rated configurations. When ordering a replacement, match your door’s exact model, section height, window stamping, and insert code; installation may require removing interior retainers and is best performed by a Clopay dealer following the manufacturer’s instructions. For hurricane or high‑wind zones, use only the specific WindCode‑rated components approved by Clopay for your door, and handle glazing with appropriate protection.
