They work as they should but i made changes to them to make them better by opening up the slot to the end so they can be removed without backing out the unnecessarily long threads on the lock knob that comes with the stops.. There are times when removing them during crown installation is needed, this makes it easy to remove and re-install them. Hint: put a pencil line on the base to show the position of the stops so they can be quickly put back on. Also on my 1 year old 12" dual bevel Dewalt saw they did not work with the the 6.25 inch crown I was installing because they would not move out far enough. I solved that by drilling and tapping another hole in the side of the saw base. There are other ways to cut crown, but I prefer the method that requires placing the crown on the saw base on an angle. These stops are a great help for that.
