Keep rivets, fasteners, nuts, bolts or other parts in order with this durable, 8-compartment tray. Trays are molded of chemical- and crack-resistant TPR (thermal plastic rubber) and will outlast inferior polypropylene ones. Curved bin bottoms make it easy to get parts out, and spring-loaded lids shut automatically. Handle retracts so multiple trays can stack. U.S.A.
