This Range Hood Backsplash Kit with Shelf protects your kitchen wall from grease, steam and other damaging effects from cooking and also creates a decorative finish to the wall behind your range. The shelf can be flipped down for use with food warming lamps (on select range hood models). This accessory can be used with any 30" range or cooktop and includes required hardware. It is designed to be installed either with the backsplash alone or with the optional adjustable height extension (Included). The backsplash alone is 20" high and will install flush to the hood. When installing the extension, the kit will cover the wall from 24" to 37" below the hood.
