## Questions & Answers

**Q: What kind of adhesive should be used to attach to the counter?**
A: Any multipurpose adhesive that is compatible with the countertop and the bracket. Typically a polyurethane adhesive or liquid nail.

**Q: what is the pre-drilled hole size? and are there holes on each side?**
A: As you can see by the picture, they come with screws, they only have holes on the one side, no need to have holes on both sides.

**Q: can these brackets be painted?**
A: The best way to paint these is by scratching the surface with 220 sandpaper then use a spray paint that is designed to adhere to plastic. (The stock finish is a platic powdercoated coating that gets melted onto the steel bracket.)

**Q: Is the finish powder coated or painted?**
A: Powder finish -- the coating is baked on and won't scratch unless you physically sand or scratch it.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect for supporting a bar countertop!
*by T***N on August 19, 2020*

What a great find and a great product! I wanted a low-profile angle bracket to support a stone bar-height countertop that would cantilever out 12" off the wall. I thought I was going to have to get this custom-fabricated, but then I found this! It's perfect. Super sturdy. Great construction. Precisely 90 degrees, which isn't easy if it's welded due to heat distortion. Great powder-coat finish. Nicely packaged.After installation, I sheeted the wall with plywood to bury the vertical legs of the bracket, and then drywall over that. What's left is a herky support sneaking out just under the stone. No one will see it or hit their knees on it.The kit Included good instructions, the lag screws (and an extra screw, just in case! Thank you!) and the #3 phillips bit which you need to use. You need a partner to help you position the bracket. Align the bracket left to right on the stud and up & down based on the back edge of the bracket. Mark the centers of the top & bottom holes with a ball-point pen. Drill a 3/16" pilot holes, and drive the lag screws - and THEN drill the center hole. It's hard to get all three to line up perfectly if you try to pre-drill all three. Tighten the top screw only. Shim the bottom end to get the front of the bracket level with the back, then dog-down (tighten) the other two screws. Re-check just to be sure. Once you have three brackets installed, it's better to line with them than the supporting wall, because your stone is planar. Now that I have these installed and feel them, I could have gone with every other stud = 32" on-center.

### ⭐⭐⭐⭐⭐ Great product!
*by N***S on May 7, 2020*

The media could not be loaded. These are super strong! Compared to the generic brands I have seen, you can tell this manufacturer is a perfectionist and took the time to make these brackets perfect. Upon opening the box and seeing the foam packaging I realized I was dealing with professionals and not some knock off brand. It was very nice to see that they provided large heavy duty wood screws and even sent an extra one. They also provided a large #3 Phillips head bit to fit these large screws. I did not have this large size Philips bit as most people wouldn't normally have. You wouldn't want to risk stripping the screw head with the most common smaller #2 bit. These brackets have a nice finish and are perfectly 90 degrees. The installation instructions were simple and easy to understand. My island countertop is 54” by 100” and weighs 650 pounds. I just needed a little extra support at the overhang so I set the countertop first, then installed the L brackets second. This method worked well but most installers would install the brackets first with a level then set the countertop to speed up the install. I love how they are super strong, hidden, and you will not bump your knee on them. I'd buy again when the need arises.

### ⭐⭐⭐⭐⭐ Sturdy and great look
*by D***T on January 22, 2025*

I bought these to support our new countertop. They match perfectly, easy and ready to install. I highly recommend these supports
