With these brackets I built a very sturdy, nice-looking woodshed in under 4 hours. They are well-made and do exactly what they are advertised to do. One piece of advice; bring one to the hardware store with you when buying the lumber; some 2X4's are cut thicker than others and if you get pieces that will not fit, it will be a pain in the rear. I was able to fit them in the store to easily find some planks that fit. The job was a breeze after that!
