Our 12" Tray Divider installs quickly to divide the vertical space of your kitchen cabinets to more efficiently store baking sheets, cake pans, muffin tins, cutting boards, serving trays or paper grocery bags. It's made of white vinyl-coated wire for durability and a low-profile appearance. It can also be used to organize a cabinet in the craft room for gift and shopping totes. Standard lower cabinets are 24" deep so the 19-1/2" depth of this divider makes it appropriate. ||Sold singly, mounting hardware is included with each Divider
