very nice brackets..very sturdy. Fits a 1x10 board perfect. Comes with everything you need and a.cool little level also. I loved them.so much I bought another pack and decided to add more shelves for my plants. It was easier to mount the shelf to the bracket then mount the whole shelf. Holds almost all my plants some are pretty heavy.

Well made brackets
Size: 11.25“, Color: black-6 pack, Size: 11.25“, Color: black-6 pack
These are nicely manufactured in that they are all exactly the same (with no variations) and with nice countersunk holes for the provided black flat head wood screws. I used a stained 1x12 #2 whitewood (Eastern Pine) from Lowes for the shelves. With these brackets solidly installed into wall studs at 32" on center (every other stud) the 1x12 shelf will easily support a heavy book load. I like the look better than the brackets that have the vertical leg below the shelf. It looks a lot cleaner. It is probably inevitable that your stud layout will result in a bracket or two needing to be installed between solid wood studs. In this case, do NOT use the sheetrock wall anchors provided with the brackets as they will pull out of the wall under an appreciable load. Instead, get some "Snaptoggle" toggle bolts and replace the provided bolts with #10-24 x 1.25" flat head machine screws in black. These toggle bolts are incredibly strong and easy to install. I am adding a postscript to my review regarding bracket spacing recommendations. With a heavy book load, the 1x12 shelf boards don't sag with the brackets spaced 32" apart, however I have found that the brackets themselves are overstressed by about 30% (they are only rated at 80# each.) Heavy books weigh up to about 36# per lineal foot so the maximum spacing of the brackets should be 24" apart. At 32" apart, they won't pull out of the wall if they are fastened into studs but they will sag a little bit back to front under this load. So I added additional brackets in between the installed brackets and now they are 16" apart at the heavy book shelf. The load on each bracket is now less than 50# but they STILL sag about 3/16" from back to front when loaded with books! No danger of structural failure and the sag is not really noticeable.
