## Customer Reviews

### ⭐⭐⭐⭐⭐ Nice brackets
*by R***A on May 5, 2025*

Nice heavy duty supports finish on them was great. The only thing is the screws they seemed ok but I was drilling through 1 1/2 white oak so the heads wanted to strip out. So I used 2 inch long lag bolts worked out perfectly . I used these brackets to support a bar area overhang on our new stone countertops.

### ⭐⭐⭐⭐⭐ When you need to hold up a lot of weight.
*by M***N on December 17, 2024*

When these were delivered I could not believe how heavy the box was. We had two large floating sinks to install in a handicap bathroom and my goal was to support the sinks with brackets that could not only handle these monster sinks but also the weight weight of a heavy handicap person losing balance and having to lean on it.... My contractor and anyone else who had the privilege of holding one of these before we installed them we're blown away by how sturdy they are. Of course no bracket is better than the wall it is secured to so were you reinforced the wall behind it. The value and look we're good.

### ⭐⭐⭐⭐⭐ Don’t need a lot of these
*by T***M on February 11, 2025*

These are heavy duty brackets which I needed to support the open end of a floating vanity. I put tile on that wall so I was able to cut the sheet rock out of the way and screw this directly to the stud in the wall. I could sit on the 2x4 frame it was supporting.
