This pivoting shore cup is excellent bang for the buck, but you get what you pay for in terms of manufacturing quality. I purchased 3 of these, and found they are not welded or drilled straight and they do not tilt the full 45 degrees. I had to trim 1/4" off the base plate to get the full 45 degrees that I needed for a brace, and then had to custom cut my wood brace to fit correctly after finding the assembly was twisted due to offset drilled holes and welding. Otherwise, if you aren't worried about angularity or straightness, this brace is excellent for the price.
