2 Pack - 9.25"L x 6"H Heavy Duty Iron Shelf Brackets, Industrial Metal Wall Mounted Shelving Supports for Floating Shelves, Bookshelves, Kitchen & Bathroom Storage - Rustic Modern Home Decor

I'm not sure if I'm using these as intended, but they work really well for getting my scrap wood off my workbench. I attached them to studs using 2" #10 wood screws. They seem super strong. They're currently holding walnut, maple, oak, and some pine as support boards. No sagging. I imagine these will hold well.I bought these particular shelf brackets because of the small lip at the front. This rack rest over my wife's car and I wanted that lip to secure the support board. I highly recommend this product!
