A multiway gravity box and door assembly is capable of selectively storing, transporting and/or dispensing different particulate solid materials. The gravity box has a partition wall to separate the box into two separate compartments each of which communicates with a separate discharge opening from the gravity box. First and second doors are slidably movable in the respective openings and a third outer door overlies the first and second doors and is also slidably movable. Pins are selectively positionable to engage the outer door and either one or both of the first and second doors to selectively open or close the first and second doors when the outer door is opened or closed.
