  • All dimensions are entered in millimeters and all outputs will be in millimeters
  • Dimensions must be entered consistently (i.e. if you enter an inside dimension for one input, enter an inside dimension for your other inputs. Do not mix inside, outside, and centerline dimensions).
  • All dimensions are to be rounded to .xxx (3 decimal places)
  • If you are not sure about your measurements please contact us.
