The wide space concave is actually a universal concave and is the only one which will allow corn to separate thru it. You can modify one with filler plates and it will do a very good job in small grains and other crops, as well. A narrow space concave can only be used in small grains, unless 1_2 of the wirers are removed for separation. The problem which then would occur would be fast wear and breakage of the wires.
