Review on Heavy Duty 12 Inch Black Metal Collapsible Folding Shelf Bracket For Wall Mounted Table, Bench And DIY Projects - Max Load 150 Lb by Adrian Retana

I originally had the idea to make a computer desk that's easily collapsible and monitors that I had attached to my wall, but decided to go against that and installed these in my small kitchen to make extra counter space. These work perfect and are very strong, they're easy to open, they're relatively easily installed. I put some larger carpenters screws into mine and i could probably sit on them. Im not going to and I really dont know if they're rated for 230 pounds but theyre very sturdy
