The Clopay Window Inserts—Chocolate—Madison Arch 613 is a decorative snap-in grille designed for Clopay residential garage doors that use insert-style windows. Identified by Clopay’s Madison Arch 613 design code, this overlay creates the classic “Madison” grid with a graceful arched top, delivering an instant curb-appeal upgrade or direct replacement for a damaged or faded insert. The Chocolate finish is intended to match Clopay’s factory Chocolate door color for a coordinated appearance across the door system. Typical use cases include replacing an existing Madison Arch 613 insert, converting from a different grid style, or refreshing the top section windows on compatible Clopay steel doors.
This insert is generally compatible with select Clopay doors that accept snap-in window grilles, including many Classic Collection and Gallery Collection models. Installation is straightforward for most doors: from the exterior, remove the existing overlay and snap the new insert into the window frame; depending on door construction, the interior retainer may need to be released to access the glazing safely. Always verify door model, panel design, window opening style, and glass type before ordering to ensure a proper fit. Handle glazing with care, support the door section during service, and avoid operating the door until the window components are fully secured.
