The Walthers Cornerstone Grain Surge Bin is an ideal addition to any diesel-era grain elevator or feed mill scene. Above the surge bin, the funnel-shaped distribution head of the grain conveyor routes grain into the proper pipe, sending it cascading into storage bins, surge bin, covered hopper or grain truck. The surge bin regulates the flow of grain into the grain dryer. The surge bin is a necessary part of any grain handling operation and will add realism to your scene. As shown the model measures: 1-1/2 x 1-1/2 x 9" 3.8 x 3.8 x 22.7cm
