These brackets hold a 4x4 wooden pole at right angles well for a sign I built. Be sure to check the mounts before using them as some of the ones I bought were slightly bent. Easy to fix. So I think the brackets could have been a little thicker metal. When I was at the store to gather supplies, I noticed that the price for the same brackets was a bit lower. I just thought the price in store would be higher. Obviously not the case.
