This fence is just what I needed to replace the useless fence that came with my old Craftsman contractors saw. It all went together better than I expected. All the holes lined up for me. I did have to modify the switch mounting plate so it mounted on one of the tabs on the new rail.The only thing that looks like a potential problem is that the ruler tape seems to be rolling or coming unglued, a little on the edge. I could see something catching on it and ripping it off.I am happy with it.
