EVERY KITCHEN NEEDS ONE The problem with most dish racks is that they take up space. Our Rolling Over Sink Dish Rack features a flexible design, rolls up like a sink mat and takes up minimal space. This makes it ideal for any kitchen. Made of stainless steel and completely covered in food grade silicone, which keeps the shelf completely non-slip. It is heat resistant up to 400 degrees. Dimensions - 20.5 inches x 13 inches
