NETWAL Folding Shelf Brackets 16 Inch, Heavy Duty Steel Collapsible DIY Wall Mounted Shelf Bracket for Bench Table Pack of 2 Max Load 150lb

Very easy to install!

The weight rating is a little uncertain about these. They say “100 lbs” at the top, but later in the description it says “150 lbs.” So which is it? And is that per bracket or total? So is it really only 50 lbs each? Or 200 lbs total? Anyway, my husband installed the set on a shelf in his workshop. He is absolutely thrilled with them. He has the extra workspace he needs, and he can easily fold it out of the way when he’s done. And the shelf feels really, really solid. No sagging. Take note that to collapse the shelf, you need to depress the catch on both hinges simultaneously. So put them within easy arm’s reach of each other. You probably would do that, anyway, but just in case you were planning on getting multiple sets to support a long shelf. Seems like a reasonable price for a solid product. Just wish the weight limit was more clear.

I agree with others that the screw holes are not terribly well placed. I have right angle adapters, and extensions in my possession, so it wasn't an issue for me. If you have basic tools, you may find yourself screwing some of these in by hand, or frustrated. If you can install them, they work as intended. My shelf folds flat against the wall, and sits nice and solid when in the up position.
