Greenmade Shelf Hook

This hook is designed to slide into the slots on either end of Greenmade 5-Tier Utility Rack sold at Costco. This hook was designed to add additional functionality to these shelves in order to hang backpacks, jackets, keys, and more to maximize vertical storage space. Each shelf can support up to 4 hooks.
