Review on YUMORE 16 Inch Heavy Duty Folding Shelf Brackets, Collapsible DIY L Bracket For Workbench Table Hinge, 330Lb Max Load Capacity (2 Pack) by Corey Bigglesworth

I was building a "market cart" for a friend who would be taking the cart to craft fairs, etc. The cart was 5' long, 2.5' wide, 3' high, but she needed to have a shelf on one end to extend the length of the cart, and it needed to be fairly sturdy since there was a chance someone might lean on it for one reason or another. The metal brackets were perfect for this application. The shelf is 5/8" poplar plywood 20" x 30", and when "open" it is very sturdy and yet easy to collapse for transport. Overall, I would highly recommend the brackets for this kind of application.
