To use the 11x13" fixture you will need the 3 holes pictured on the left and right side of the lower part of the station, the 13x16" also needs the 4 holes below the 11x13" holes. If you do not have these holes, order the drilling jig when you order the fixture. The drilling jig will locate the holes on your station and allow you to add these holes easily. The jig also comes with the correct size drill bit.
