Using your Bobrick B - 527 waste door is easy. Just open the self - closing door to place trash inside. When mounting, make sure your counter is between 3/4' and 1 - 1/2' (19 to 38mm) thick and there's at least 4 - 1/2' (115mm) of clearance below the mounting surface. Remember, you'll need to provide your own waste bin and housing. To keep it in good condition, clean the satin - finish stainless steel regularly with a mild cleaner. Avoid using abrasive materials as they could scratch the surface.
