so 9 inch slides are not easy to find. This was my second purchase as the first one fell apart. Of course, I'm no pro and don't know anything about drawers, so keep that in mind. They're cheap so I'd double your purchase so you don't have to wait for the ball bearings to fire all over the garage. So if you really know what you're doing, you're good to go. Otherwise, buy in bulk. And disappointment awaits!
