To Calculate the List Price of Belts

Step 1 - Multiply the number for the width and grit by the belt length. Round all fractional length and width measurements to the next larger inch.
Step 2 - Add joining charge.
Step 3 - Multiply the results of Step 2 by the apporpriate material multiplier listed above. This is the list price per belt.

* The joining charge for belts 2-1/4", 2-1/2", and 3" wide by 38" long or less is $.84.
