I was careful with the installation, using a level (horizontal and vertical, measuring twice, etc. but still the shelf folds only 95%. It binds for me when nearly closed. The tolerance to get the front of the horizontal folded down over the bottom of thevertical -- is very tight. If it does not align very well, then the shelf won't go flush against the wall. So, if you use this product be super careful when leveling/measuring, etc. For my needs in the garage, this slight issue was not a big problem, but in the kitchen etc., might be a problem.
mine is 1 inch at the top and 1 and a 1/4 at the bottom of the bracket
It is 750 per pair but not tested for three.
Yes you can. My purchase of this item was to create on my metal counter island an extended folding table space on both sides. I pop it up as a eating space with my bar stool chairs or for extra counter space when baking or when entertaining, then close it up when not in use. Additional items used were boards and screws to bolt to the inside of my island cabinet to secure the bracket and of course the boards used for the counter top area. I've attached my photo.
I believe the 12" is fine but it depends on what is going on the shelf. The brackets and board are heavy duty and can easily handle 100 lbs. If you are going to put a lot of heavy items on them go with the 16".
I don't think so. To unlock, it goes a bit past 90 degrees, so the shelf would be tilted down a little if mounted upside down. And it wouldn't lock when folded. I think gravity would tend to open the shelf.
Very nice brackets and yes they will last outside
I feel your pain. I had to lay down some painter's tape, then mark the hole, remove the bracket, drill a pilot hole for the screw, place the bracket back up, then install the screw with a really long hand screwdriver. Of course, by doing all these steps, it didn't line up well. Good luck.
They can handle the weight but the brackets are designed to anchor the shelves with 4 screws each. How are you going to secure the glass shelves and address the aesthetics of the bracket top?
