Works as intended
Style: Black 6 Pack, Size: 7.25 inch
It works as it should. I does look like it bends down after screwing to the wall but the level seemed spot on. Either way it hold up my shelf great

Fantastic slimline brackets
Style: Black 12 Pack, Size: 9.25 inch
We're hanging some shelves that will hold some weight and wanted a minimal amount of shelf to show. It's about what's on the shelf, not the bracket. The black metal adds just a touch of style against the white painted wood shelves. They look great. The best part is that the screws go right into the middle of the shelf which makes it easy to hit the center of the stud. Standard box store lumber fits perfectly. A 1 x 10 fits like a glove and the small lip finishes off the classic look. Comes with all sorts of mounting hardware and the screws are decent quality and went in with no issue or stripping. I usually have to buy better screws but these were fine. At this price it really was an excellent deal and they are heavy duty. Win Win Win.
