I see in you catalog that you have 21 " and 22". The one I need is 21" 1/2 does it make a difference.

Hello,

You should be able to round up and use either our S600-22 or S900-22 spiral balance, depending on if the diameter of the plastic tube cover on your balance measures 3/8" or 5/8". Take a look and see what you think. Thanks for posting!
