I bought this for my old Craftsman table saw. I was a bit worried that it might not fit the table’s miter slot; but right out of the box, it fit when I removed the roller guide. With just a bit of adjustment to the ball guides, it is snug but still slides nicely. I can’t wait to try this out to check the accuracy! Made of quality materials, and appears very durable. Very easy to assemble and set up. Will check back later if there are any issues.
