Simple, gorgeous, heavy duty
Style: L Bracket w/ Lip, Size: 11.25", Style: L Bracket w/ Lip, Size: 11.25"
I needed to mount a heavy wood shelf and wanted something with clean lines that would keep it safely in place above a bed. These are heavy duty solid iron and I mounted them into wall studs. Instructions didn't say what size drill bit to use, but 9/64" worked perfectly. The package has drywall mounts too, but I can't imagine they'd hold safely. Put the shelf up and it looks great! The lip on the front of each bracket is another plus that keeps the shelf from slipping forward.

Beautiful shelf brackets
Style: L Bracket w/ Lip, Size: 9.25" x 6", Style: L Bracket w/ Lip, Size: 9.25" x 6"
I am extremely please with the brackets but had a hell of a time installing them. It is only me, so I had to be careful with making sure they were horizontal, etc. The little levelers are cute but definitely not a help. Use a standard size leveler. Also - I used the anchors provided for the drywall and they punched in two big holes. I ended up buying a different kind of anchor to put in the middle bracket (my first intentions were to use three brackets to make sure the shelf would hold). I was lucky that the size of the shelf I wanted coincided with the 2x4s in the walls so I was able to anchor the brackets and shelves to the 2x4s in the walls., so my shelves are very sturdy. I bought 3 sets intending to put up 4 shelves with 3 brackets but only did 2 shelves with 3 and 2 brackets, respectively. I like the look so much that I am keeping the ones that are unused and installing them in my bedroom for my books. Right now, I am extremely happy with them.

Sturdy/Heavy brackets
Style: L Bracket w/ Lip, Size: 9.25" x 6"
We wanted to replace our awful white wire shelving in our pantry and purchased these brackets. Had the wood shelves cut to fit so very easy to install the shelving on top. The lip at the end of the bracket holds the shelf so the brackets do not need to be attached to the shelf. The brackets are very sturdy, heavy metal so they definitely hold the wood shelves and pantry items. Only complaint -the screws that are included. Some of the screws stripped or broke while trying to attach the brackets to the wall studs. They do include an extra screw in each box I guess for this purpose but we still had to purchase additional screws to replace the broken ones. Very frustrating but the finished result looks great and the brackets were an easy fix to replace the old shelving.

Sent more screws when needed!
Style: L Bracket w/ Lip, Size: 9.25" x 6", Style: L Bracket w/ Lip, Size: 9.25" x 6"
Screw heads frequently stripped, and on 3 the head sheared clear off. All this despite drilling pilot holes and lubricating screws.
The seller was wonderful though and sent extra screws at no extra cost. Looks great and holds well now that complete!
