Question: From the picture it doesn't look like a shelf would be parallel to the wall in the closed position. How wide is it in the closed position?
Document: We bought these brackets to make a shelf for out cats in the sunroom. We wanted something that was strong and folded out of the way. This was the right choice. Mounted to the wall just as the picture shows the bracket sits under window molding out of the way when not needed. The bracket strength was enough at 50 lbs per set. I am buying similar brackets for a work area shelf as well with a higher work load. I would buy these again, Oops, I already did.
Worked as advertised. Easy to install and is very sturdy  I would recommend them to anyone wanting a shelf bracket.
These fit the bill for a small extension shelf by the kitchen counter in my camper. A OK and for this application, you cannot do better for the price. Good fit and finish. I recommend and if you knew me, you would know that I am a particular old codger.
This is a very useful product to use while building shelves that will fold away when not in use. I constructed a shelf for an IT closet where the laptop has a place to sit while working configurations on the equipment. When finished it just folds away. The product is strong and stable. You can't get these just anywhere. I took the picture of these to HD and Low and got several blank stares.
So far the bracket seems to be preforming as said. I like it. Maybe a bit heaver. Again thanks Bob R.
Wanting to build a drop down extension off my breakfast bar and there was nothing available locally.Ordered these thru Amazon and am very pleased with how well made they are made. The pair of these would probably support my weight.Very satisfied.
Was looking for folding brackets for months. Stumbled across these. Holds and folds my 5 foot breakfast bar. Good value for price and does the job well. Gave it a 4 only because I would have liked a selection of colors.
These shelf hinges are the perfect replacement for my fold-down lunch counter that is mounted to my food concession trailer.
I was going to spend 300 for a pair of special hinges for a breakfast nook swing up shelf....crazy! These hinges are very strong and work perfectly. Very happy!
I wanted to build a folding shelf in my laundry room, but I couldn't find these brackets in any store (even Home Depot), so I was pleased that I can always find what I need on Amazon.
