The best way to find the right replacement parts for your saw--whatever model you may use--is to know your saw's model number. You can find that information in the original owner's manual if you still have that laying around, or you can search a bit on your saw to find the information you need.
You'll want to look for a sticker or metal plate somewhere on your saw. For table and band saws, check near the top of the unit or near the motor. You'll most likely find that information there. On hand-help saws, check the manufacturer nameplate, and on the back and sides of the saw for a sticker with all the information you need.
If you're still having trouble finding the number, give us a call and one of our customer service reps will happily help you find the information you need.
