The Original Granite Bracket Large Shelf Bracket (Aamerican Made Steel,18x10, Black) 1 Count, Strong & Durable, Ideal for Kitchen Floating Shelves, Bathroom Vanities, Home Projects, DIY Projects

I have bought 2 sets of these and have no concerns when it comes to quality. Truly over-engineered and rock solid. I have used these for a studio desk with 10s of thousand of dollars worth of equipment under their support. I use these with heavy butcherblock table tops so I know they can hold the weight. Heck I tested after install and sat on the desk. I am 6' and 250. I recommend these to anyone wanting simplistic design and solid craftmanship. 🔥

Been a stone installer for over 20 years. Sometime before starting that, was a union shipyard welder. I love these brackets.Only caveat depends on your use case: the weld on the back outside of the bracket isn't ground flat, can hold the top of the bracket off the wall slightly. Mostly, that shouldn't be a problem, but in some scenarios, you might need to grind that weld flat, as I have.Small thing, but for the price, I would expect them to do a better job on that detail.These are a little pricey, and I usually just make my own, but if you have the time to wait for the order, don't have a shop handy to make it for you, and don't feel like - or can't - make your own, this is a very good option.

Heavy duty steel shelves bracket. It is designed to hold up lots of weight. Would recommend to anyone who is looking for strong shelf support. You can put your heaviest tools in your garage on it.

It's a very sturdy bracket that's made with thick steel. I got the 24" long version which worked perfectly for my new 25" wide quartz countertop piece. I would buy again.

Well packaged and arrived in perfect condition. Can't say enough about how sturdy they are. Price was great too.

1/2" thick iron on top was a little more than I was looking for that made it heavy to mount overhead. I used it to mount a Boys in the Boat 8 man rowing Shell in a Museum.The screw holes next to the brace were a little too close so my 5" LedgerLok screw heads on one side of the brace didn't screw in all the way. They could have made them 1/8 to 1/2" away from the center of the brace easily instead of so close to the brace support.

As another user noted, there are no holes on the shelf side. Presumably, when using it to mount a granite countertop one uses an appropriate adhesive to keep it from scooting sideways. I drilled holes using a titanium bit, drill press and cutting oil, and it went fine (work hardening is not an issue with this material). I would be uncomfortable doing it less well equipped, say with just a hand drill.Perhaps overkill for my use too, but it was the only one with a gusset. I mounted a shelf for a very heavy record player (SOTA turntable). I thought I could do better than the silly overpriced turntable shelves sold by the high end audio dealers. No hint at all of shaking--in fact, I can attempt to shake it while a record is playing, one of my design goals. For the shelf I used a piece of 1-1/2" butcher block, which I didn't want to glue to in case I want to move it. It seems to me drilling a hole or two on the shelf side would not interfere in the least with using it with an adhesive. It would have been nice to include them. On the other hand, I needed nowhere near all the holes or included screws to mount it on the wall. Two screws each firmly in the wall studs, and it isn't going anywhere--less than 100lb total weight.Regarding ease of installation, it is very nice the top holes are precisely 3" from the bottom of the shelf. Since holding the bracket to the wall and drilling through the holes is really out of the question without an extra pair of hands (they're really heavy) I simply drew a level line 3" below where I wanted the shelf. A precise even metric measurement would have been equally helpful. But I dinged it one star for lack of shelf holes. Also, they strike me as just a bit pricey.

Used 26” brackets for supporting my heavy butcher block with 33” width and easily supports the countertop. Make sure you attach to the studs in the wall. I used heavy duty 2” Velcro strips to secure the countertop from sliding because I didn’t want to glue or drill on the brackets or countertop in case I have to move it. I suppose you can drill or attach some fasteners which will be more secure. Product was pricey and I bought two. However, these are heavy duty and you get what you pay for which justifies the price and I would buy again.
