A 36" (914 mm) piece of Snap-in-Filler is provided with each Deluxe Header Kit, and is also available for replacement in both 36 and 72" (914 mm and 1.83 m) lengths. Snap-in-Filler puts the finishing touch on the installation of the Deluxe Header. By simply press fitting the Filler into the Header directly above the door pocket, you create an even sightline of metal, and fill what would have otherwise been an unattractive Header pocket.
