Safety grain bin door latch system

A safety grain bin door system for a grain bin having a sidewall the system, comprising:

• a door frame connected to the sidewall;
• the door frame having an upper frame member, a lower frame member and opposing side frame members;
• an inner door;
• the inner door connected to the door frame;
• wherein the inner door moves between an open position and a closed position;
• the inner door configured to transmit hoop stress across the opposing side frame members;
• an outer door;
• a pair of hinges connecting the outer door to the door frame;
• wherein the outer door includes a handle assembly;
• wherein the outer door includes a first set of connection assemblies positioned on a left side of the outer door;
• wherein the outer door includes a second set of connection assemblies positioned on a right side of the outer door;
• wherein the pair of hinges and the handle assembly are configured to be connectable to the outer door by the first set of connection assemblies and are configured to be connectable to the outer door by the second set of connection assemblies, thereby permitting hinges and handle assembly to be connected to either the right side or the left side of the outer door;
• wherein the outer door moves between an open position and a closed position;
• a safety mechanism;
• wherein the safety mechanism provides a visual indication that the inner door is in the open position when the inner door is in the open position and the outer door is in the closed position;
• wherein the visual indication the safety mechanism provides that the inner door is in the open position is a first color;
• and
• wherein the visual indication the safety mechanism provides that the inner door is in the closed position is a second color that is different from the first color.
