I purchased these for storage in our very full garage. I have no problem with the brackets themselves but I do have a couple of suggestions for the manufacture. First of all, there are no anchors in the packaging. (Anchors are shown in the illustration on Amazon). I was installing mine into studs in the wall, and didn't need any, but that leads me to my next problem. The enclosed screws have such a small phillips head that they are actually hard to get to screw in even with pilot holes. I had to take vice grips and wind the screws in to their appropriate depth, (without the bracket), back them out again and even then, they were very hard to screw in with either of my cordless drills. I know that it's probably cents on the dollar but how about using hex-head screws instead? The bracket is in the way of the top screw and so you need to use an extension or long phillips head attachment.
To bolt on the shelves there are only 3 screw holes. I was using 2 pieces of wood and so one of them only has 2 screws total in it to hold it on. The company does supply screws for this, but you have to have approximately a 3/4" or 7/8" thickness for your shelf, otherwise you will need washers, (not included), to install your shelves.
This is a wonderful product which could be even better with a couple of small improvements.

Just what I wanted. Works good.

The media could not be loaded. I have been on a garage organization bender. I needed a workbench that was low profile and did not take up valuable floor space. I decided to build a floating bench that did not need legs directly resting on the floor. After searching around for different types of wall brackets, I came across these heavy duty, fold-able, brackets. I ordered two pairs of brackets. The brackets arrived quickly. One of the boxes was slightly damaged, but the contents were undamaged.

It was immediately noticeable from their heft that the brackets were of good quality. I have no doubt that each set will hold their claimed 500 lbs. of weight. In the opened position, the brackets measure 23" front to back and 21 and 1/2" vertically (both measurements are slightly shorter than the product's description) The brackets are 1 1/2" wide and about 1" thick. After fabricating the top for the workbench, I spaced the inboard and outboard brackets at 46" to accommodate the items I wanted to put under the bench. The brackets easily handle the load span of the bench top and keep the top from flexing or moving from side to side.

The brackets were relatively easy to hang. By following the directions and making sure the tops of the brackets were all level with each other, it was easy to mount the bench top to the brackets. I left the wall mounting screws
a little loose while I positioned and screwed the top to the brackets. I tested folding and unfolding the workbench a few times and tightened all of the screws once I was satisfied with the bracket's operation. Even though there are four (4) individual brackets, it is not difficult to fold the table down and lift it up (as seen in the video).

The manufacturer has addressed complaints from older reviews by adding a pilot hole in the top bracket to access the upper most mounting hole on the wall side of the bracket. The bracket would be easier to position if the top of the wall-side bracket were square, instead of round, but this is a minor complaint.

In summary, the brackets are very sturdy and easy to use. Given the load rating for these brackets, you would be hard pressed to find a fixed wall bracket that performs as well as these fold-able brackets. I would highly recommend this product to anyone looking for a space saving mounting option for a shelf, bench, or table.

Exelente producto

Used on my delta saw to extend the saw table on the back. Works great. Easily holds up anything I have had on it like a full sheet of 3/4 plywood.
