These worked perfectly to replace the triangle pieces under my kitchen island. They are very heavy! Sturdy enough to hold up the granite countertop for the island. I do wish the screws it came with were black instead of silver.

It's a solid piece of steel. I used it to hold up a counter piece on an outdoor bar. Very sturdy.

These brackets were used a large bar we built for a customer. They were really well constructed and a great price. Quick delivery like always with Amazon. I used to have to custom order these for kitchens 2 weeks in advance.

Very heavy duty - thick and rock solid. I have purchased much more expensive versions for other projects and these are equivalent if not better quality. They are all very close to a exactly 90 degrees but anyone who has used these knows that it is extremely challenging to get them installed precisely in the first place so shims may occasionally be needed if the framing isn’t perfect to begin with. I used these for a wall bar and cut away the sheet rock over each stud and offset the bracket to use the two outside holes and center hole. The countersink on the bracket will determine the final position so it is important to line them up and drill pilot holes. I mounted the outermost two, clamped a board in pace and then clamped the other two to it in order to ensure alignment. The screws are very hard. I shattered two impact bits driving them home. I ended up using a softer bit (cheaper) so that the screws didn’t strip and the bit took up the impact. I liked these enough I buying another set.

It’s safe to say the wall is coming down before these shelf brackets give. We used 1.5” butcher block counter tops cut down to size for our closet shelves. I wanted a bracket that allowed full use of the shelves below and didnt want a support across the shelf. I was concerned about durability but after reading the reviews on these I gave them a shot. They didn’t disappoint. They’re incredibly heavy, come with all the hardware, and they’ll serve their purpose. I was especially happy with the hardware. I typically always use my own hardware but after seeing this included hardware I gave it a shot. You get a few extras but none of the screws stripped out going in to the studs, and they are definitely quality screws. We will be using the same brackets for our pantry shelves as well.

It's a strong set of brackets, but we needed something else for our project. We would buy again for a different project.

Installing a breakfast bar that’s 20” wide, very solid, not cheap but one of the best values when you need an exceptional firmness. Had installed cheaper brackets from box store but countertop could move a bit as they were too thin, so got these. Very satisfied. Was able to secure into studs. One note is it wasn’t too difficult to add a few holes for adding extra screws from bottom to secure the countertop. These come w just 2 holes, and just took few min for each hole. So everything worked out well.

Needed an extended overhang with a quartz countertop. Used two of these, and a 10mm rebate into the underside of the countertop. Everything worked great, I have confidence in the strength and robustness of these supports. They were nicely powder coated, and even though I hid them as best I could, they look pretty impressive if you peek under the countertop. My only suggestion is some extra options with length, but these worked great for me and the price was great compared to some others. They also arrived faster than expected. Thanks
