Review: The best out there - These are awesome... very very sturdy and durable, great quality for a great price, hardware is solid and included!! Don't bother with any other brand, these are heavy duty
Review: These are the ones you want - I've used different sizes of these Claimed Corner brackets around my house, along with trying similar styles from other brands on desertcart, and can say these are easily the best ones I've seen on here. I have some of them supporting 7 foot long pantry shelving that holds heavy jars and other food products, with no bend in them at all. You'll want to space them closer together for heavier shelves is all. A couple of differences with these that set them apart are - they are not painted. They have a nice dark, almost black, natural finish that doesn't scratch away easily, and is very uniform but rustic looking. Other ones I've tried have had sloppy paint that comes off easily. Also, the screw holes are already counter sunk so you get a nice flush finish when you put the included screws in. And speaking of, the screws are top-quality, strong, and they even include and extra one in each size. My only request is that they'd offer more sizes with them. It's be nice to have some that extend to 8 inches on both ends, and perhaps a smaller size as well. Otherwise a great product.

### ⭐⭐⭐⭐⭐ Top quality
*by J***E on January 24, 2021*

These brackets are well worth the money! I was looking at similar brackets at a big box, brick and mortar store for a kitchen shelving project. These were similar but cheaper. The difference being that they didn’t hold as much weight. This wasn’t a concern for me as I was attaching to furring strips instead of studs, which were not centered so I had to use more brackets than necessary to give it a more centered appearance. At 75# per bracket weight will never be an issue. These also came with their own screws and anchors which the other store did not. I was not able to use them for my project, again because of the outside walls being block with furring strips, there wasn’t enough air space between the drywall and the block to accommodate the length of the anchors and screws, but this is another economical addition to buying these brackets. I would definitely recommend. Good quality, durability, style and function.
