Suncast Shek shelf bracket

Bracked remixed from hook that I put in my Modernist 7x7 shed. Has two spots to screw in a shelf (I used a 1x6 board) and another screw to put into the shed, I used about a 1 and a 1/4th inch screw and it was about perfect. The holes are a little large so may need a washer depending on the screw. Works decently enough, a little janky but with the screw in on the top it works pretty good for a simple small shelf. Just space them out and cut a board to size I spaced 2 screw slots and I believe it was about 19 inches.
