Grizzly/Shop Fox Zero Clearance Table Saw Insert PW945 - 13-5/16" x 3-11/16" x 1/2" - Premium Woodworking Accessory for Precision Cuts | Perfect for Cabinet Making, Trim Work & Fine Woodworking Projects

I bought this because I couldn't find a zero clearance insert in-stock anywhere on-line. The dimensions were the same as the opening I measured on my saw and it indeed fits my Jet JTAS-10. There are no screws on the side to snug fit the opening but none was needed. The front to back has no adjustable screw either but the one pin on it fits well. I liked the fact that cutting through it didn't send toxic fumes into the air, like the resin ones do. I did need to insert a 6" blade to start the cut since my 10" blades were too tall to place the blank in the slot. Not a big deal. I was easily able to drill a finger hole through the blank and routed the hole with a round over bit to eliminate the sharp edge.I like these so much, I'm going to buy more for my dado blade, thin and full kerf blades.
