They don't come with instructions. You have to be careful not to overtighten the screws or you'll deform the track extrusion and form a bur that will make it harder to slide. I store mine in the track because they wouldn't be protected in the saw bag and would get bent but I have the Allen wrench in my saw bag where you have to dig to find it. It would be better if the Allen wrench stored on the saw for changing blades would also work with these.
