I used thes to create an outside bar. They keep everything up off the concrete so I can wash down right underneath the bar. I used the 4×4 ones for the cabinets. The only problem is that the bolts rise up too high for the cover plate once they are tight. I took my grinder with a cut off wheel to solve this. However it was difficult with the 4X4 s to get the grinder blade to fit. I had to grind down the blade to fit. Other than that these are great. I would have paid 2 to 3 times as much for Simpsons.
