Just what I needed
Order was quick and easy, package arrived quickly, part fit like the OEM, and my bench sander was back as good as new. This is a much better way to find the parts and have confidence that it will be right than gambling on that other online giant...

Great part
I spent over 30 minutes talking to Delta, trying to locate this part. Frustrated, I ended the call and went to the internet looking for a "replacement part" when I found your website, had the belt ordered and in my mailbox within a few days. Excellent service, would highly recommend your company.

Perfect fit
I shopped all over for this discontinued part for my belt sander. I was so happy to be able to salvage my perfectly good sander with this discontinued belt saving my tool from a junk yard destiny.

The replacement part was great, looks better than the one that broke. The Delta instruction manual was terrible as well as trying to get the proper size hex that was long enough to fit through the access holes. My hex set was 4 inches long and really could have used a straight hex of 6 inches long with no elbow. Its done now so hoping the rubber belt will last a long time.
