This is a Carlisle dishwasher rack. Made of thick polypropylene, it's tough and resistant to damage. Despite having gone through dishwasher cycles, the rack we're selling hardly seems the worse for wear. The marks of abrasion aren't apt to make a difference, since this rack is made for utility, not for display in your china closet. 19-1/2" x 19-1/2" x 8-3/4" high, with each compartment 3-1/2" x 3-1/2" x 8" high.
