## Questions & Answers

**Q: Can I use these outside? Are they weather resistant?**
A: These are powdercoated steel just like an outdoor pool fence. Any scratch or chip in the finish will be a location for humidity to get in and start oxidation eventually especially around the screw holes. If you don't want to worry about having anything steel outside eventually oxidizing you can dab a little paint inside and around the screw holes and over the screw heads to reduce the probability of moisture introduction.

**Q: What size screws are used for these brackets?**
A: Comes with Phillips flat head screws in black finish.
7 each 3/4" long #8 screws
7 each 2 1/2" long #14 screws
Since the #14 lag screws must use a large #3 Phillips bit for installation, the #3 bit is also included to use in your drill.

**Q: Is there any wobble to these after they are mounted?**
A: These brackets are massive and will not flex one bit. You could use them as car ramps they are so sturdy. The wobble you might be asking about would only have to do with your mounting surface. Some mounting surfaces are weak and need a piece of wood backing placed inside the cabinet to add strength. I've also seen people add a little liquid nails calk to the vertical  mounting surface if they could only use drywall anchors and didnt have any decent wood backing in their particular install.

**Q: how thick is the steel, i see no indication**
A: 3/8" thick

## Customer Reviews

### ⭐⭐⭐⭐⭐ HEAVY Duty
*by S***N on January 12, 2025*

This brackets are industrial weight and very well made.

### ⭐⭐⭐⭐⭐ Stout and easy install!
*by A***O on April 19, 2022*

Great item.! I recently bought a bathroom vanity. Solid wood with countertop and HEAVY. The store employees loaded it into the back of the truck and off I went. I really had no idea of the weight and while I was unloading it at the house I dropped it on the corner and broke the front and left lower fascia boards. Tried installing it without and it was about 4” too short. Looked like a child’s toy. I was going to try rebuilding the bottom so I tried looking for ideas online. One video was how build a floating cabinet and noticed that only the reinforced framing was the only difference from a standing vanity. It looked really good and that’s when I decided that was the way I wanted to go. Had to do some reinforcing of the cabinet walls just under the countertop but that was easy. Held the brackets up to studs, marked the outside and cut the drywall to fit and mounted the brackets directly to the studs with the face flush with the drywall. Not that that mattered because they can’t be seen anyway but, still looked like I had planned it that way from the beginning. Lol. Thanks

### ⭐⭐⭐⭐⭐ Excellent quality
*by L***O on February 25, 2024*

After wasting time running around Home Depot and buying brackets that ended up not being at a 90 degree angle, I decided I should pay a higher price to get a solid quality.I'm so impressed with how strong those are. They come with the needed screws and bit, so you don't have to buy separate things for installation. And the finish is nice, with no sharp edges and well painted. Packaging is exceptional, with tailored insolation material for protection.This product and seller are helping me not to loose hope in Amazon. Thank you very much!
