They are perfect, exactly what I was looking for. These brackets are buff! I purchased them to help support a wall desk that I am building.

If the brackets you’re using don’t have a three-screw configuration (two screws proximal to bend, one screw distal), then it doesn’t matter whether you put the brackets on top or bottom - except that, as has been noted, the screws holding the shelf to the brackets will be bearing the weight of the shelf, which is probably not a good idea.By: Michael ✔ Verified Buyer from: Houston, Tx on: July 6, 2022 Since there’s only one screw in each bracket that’s bearing all the tensile load in this configuration, the load capacity is reduced (assuming the screw pulls out of the wall before the bracket itself fails). Now the two screws immediately above the shelf aren’t bearing any tensile load (the bracket is pushing against the wall here), while the single top screw (10" above the shelf) is under tension. Suppose instead that I had installed the brackets above the shelf. In this configuration the two top screws (immediately below the shelf) are under tension, while the bottom screw (10" below the shelf) isn’t really bearing a tensile load the bracket is pushing against the wall at that point. I used stamped sheet metal brackets, and these each had one wall screw at the bottom, and two wall screws at the top (immediately below the shelf).
I recently installed some shelves/brackets in my garage, with the brackets under the shelves. the vertical height of the bracket’s footprint (distance between screws) on the wall the distance of the weight from the wall A free-body diagram on the shelf bracket will show that whether it’s anchored to the wall above or below the shelf, the forces on the wall attachment screws will be a function of: …and the screws attaching them to the wall will be under less outward force.
