A storage box comprises a housing with open ends and a tray that slides out either open end and up to at least fifty percent or up to at least sixty percent of the length of the tray may slide out either open end. Latch members operable from either open end of the housing selectively hold the tray in a centered position and can be released to allow the tray to slide out a selected end of the housing. Multiple latch member mating members may be associated with the housing for selective engagement by the latch members to latch the tray in multiple extended positions between the centered position and fully retracted positions out either the first or second open ends. Latch engagement members mounted on the doors engage latches connecting the tray to the housing when the doors are shut to prevent the latches from becoming unlatched when the doors are shut.
