These track guides are designed to work with the E Emerson straight edge clamps. They will attach to a piece of 1/2" plywood with #6 screws and let you make your own saw or router guides. That is what I did, I turned it into a track saw. I took the short ones and attached pieces to indicate the saw cut location. Now you don't even have to calculate the offset of the blade and straight edge.
The plywood acts as a zero clearance insert, so the cuts are very clean. It makes for fast, easy, and clean cutting of sheet goods.
