These stops are a GREAT addition to my Dewalt compound miter (DWS780). They are well constructed of heavy duty metal that precludes even the slightest amount of "give" when in use.  The only shortfall (literally) is the size of the mounting slots. These stops attach to the sides of the saw with large wing-nuts (provided). The mounting slots could be another inch in length to allow for slightly larger crown moldings, but then how many times do we deal with six inch moldings?
