ABSTRACT:
A door for a grain bin having a container associated therewith which is adapted to be connected to a grain bin and extended into the grain storing portion of the grain bin. An opening is disposed in a lower portion of a rear wall of the container and a front wall of the container leading to the outside of the grain bin is removable and is optionally transparent. A grain port in the top rear wall of the container has a sliding gate associated therewith for opening or closing the grain port or metering grain through the grain port. An extension spout is formed on the front bottom of the container for selectively extending the bottom portion of the container, thereby facilitating a selectively controlled flow of grain out of the grain bin.
