YUMORE L Bracket, 4x4 Inch Max Load: 25lb/12kg Heavy Duty Stainless Steel Solid Shelf Support Corner Brace Joint Right Angle Bracket, Pack of 4

I had ordered a mounted school desk for my son to do his homeschool work but the hardware they sent to mount it would not have held it at all. I went in search of a bracket that can hold up the desk as well as some pressure from laptop and arms. I found these brackets, at 35lbs max load each. They are very heavy duty, well constructed and have pre-drilled holes to make mounting very easy. I used all four of them on the bottom of the desk/wall and it worked fantastic. No problems with using screws. You can hardly see that they are even there. I'd recommend these brackets for any support needs.

Good brackets. However, isn't the recessed side of the holes, designed to accommodate the screw heads, supposed to be on the bottom, not on the top side of the long leg? Since the shelf goes onto the bracket, and the screw goes from the bottom up.

I cannot believe how strong these brackets are. I ordered stainless steel brackets because I was using it in my engine bay to mount an oil catch can. I didn't fully expect them to be stainless steel because of how inexpensive they were. They are very much stainless steel. Perhaps the strongest metal I have ever worked with. I tried for over an hour to drill a hole through One of these with a brand new set of bits, and two different drills (an 18-volt Ryobi and a 20-volt DeWalt). Eventually I just gave up. The photos shown are of the absolutely obliterated set of bits from trying to get a hole through these brackets and the hole that never was on the bracket. I even tried drilling it from the other side once I had a hole going. No dice. These things are pretty incredible, if you need strong stainless brackets, these are the ones.PS. I ended up using the hole on the bracket to drill a new hole into the catch can's bracket, which was aluminum. That was easy as pie.

A simple sturdy right angle stainless steel bracket suitable for light duty applications (e.g., mounting an outside thermometer). These are standard decent PRC quality (under transnational corporate profiteering, almost no fasteners are made in USA or EU, mostly PRC). To install using the supplied screws and plaster/drywall/stucco/concrete inserts, one does need a hammer drill and masonary bit making it not easy for most homeowners.

We purchased these to help us anchor some cube style shelving units to the wall for babyproofing. The brackets that came with the shelves were small, and seemed like they would pop off easily. These brackets certainly did the job. They are affordable, yet sturdy and anchored the shelves to the wall perfectly.

I needed non-corrosive, exposed shelf brackets. These look great and are quite strong. I only wish that the manufacturer would have provided some information on what drill size to use for the included wall inserts; rim-less, they are not like any that I've seen before, and securing them in drywall before screwing the brackets on is not obvious.

Brackets were pretty sturdy and will do the job I needed them to do. However, the hardware (screws) that came with it are completely useless. Many couldn't be used because the holes in the screws themselves were sealed with extra metal. My recommendation is to use the brackets with your own screws and anchors. Luckily I had the right fitting screws at home. The price was alright, but it would've been better with decent screws and anchors.

I used these as support brackets for an 8x8 utility enclosure so I could mount the 3-inch box to be flush with the wall sheetrock. The brackets didn't have any manufacturing burrs, did not lose shape under medium stress, and the pre-drilled holes were recessed for allowing a snug install. In my case, I was using stainless nuts and bolts to secure the box, so had to drill the holes slightly larger. While the ones I've installed will never bee seen again, I think the appearance of the brackets is perfectly acceptable for an exposed usage such as open shelving.
