Bar bottoms should be within plus or minus 0.125" of the bottom edge of the clear zone. The clear zone is 0.625" deep, measured from the top edge of the piece. The right-most FIM bar should be 2" (plus or minus 0.125") from the right edge of the piece. Bars should be 0.5" minimum and 0.75" maximum in height and at least 0.03125" plus or minus 0.008" wide.
