I bought my table saw a couple of years ago, and had they told me then that there was this extension, I would have bought it then. Very easy to install and adds an extra 12 inches to the left side of your saw. Make sure when you install it, you leave the screws loose until you retract this extension. Pushes up nice and tightly to the saw and only sticks out roughly 2". Makes cutting a half sheet of plywood a breeze. Bought both the rear and side extensions.
