Clopay Window Inserts — Walnut, Ultra-Grain — Grille on Arch1 are genuine OEM decorative snap-in grilles for Clopay garage door windows. They create the “Grille on Arch1” look—rectangular muntins carried into an arched top window—delivering a warm, wood-look aesthetic that matches Clopay’s Ultra-Grain Walnut factory finish used on steel garage doors. Ideal as a replacement part or visual upgrade, the insert refreshes window style without changing the glass and is designed to mount on the interior side of the window frame. Clopay’s decorative grilles are removable for easy cleaning, helping maintain clear glass and a crisp, finished appearance.
This insert is intended for select Clopay doors that accept insert-style window grilles, including many Classic Collection and Gallery Collection residential steel models configured with Arch1 window openings. Because window systems differ by door series and glass lite configuration, confirm your door collection, window shape (Arch1), and finish color before ordering to ensure compatibility. Installation typically involves snapping the grille into the factory window frame; follow Clopay’s model-specific instructions and secure the door (and disconnect the opener) before working on any window components. Using an authentic Clopay insert supports proper fit, color consistency with the Ultra-Grain Walnut finish, and a cohesive look across the garage door.
