A (4L) V-Belts

1/2" wide classic industrial belts that are constructed from pre-stretched polyester cord. This style belt is produced using two different part number systems ("A" and "4L"). To select your belt part number, use the inside circumference measurement of your belt for the "A" part number or the outside circumference for the "4L" Part number. Example A18= 1/2" wide, 18" inner circumference belt. Example: 4L200= 1/2" wide, 20 inch outside circumference belt. Both of these belts in the example are the same belt but show how the two ways the different part numbers come together. All belts are listed here with outer circumference measurements.
