Review on MroMax Stainless Steel Corner Bracket Industrial Hardware by Tyler Parker

I used these to reinforce a frame that I wanted to wrap in canvas. (to art) They did their job. Feel decently strong enough. They're small, so I can't imagine using them other than to hold a shelf to keep it from falling in an earthquake, or to reinforce a frame that doesn't support weight. For the price they are worth it. I bought 50 packs when I needed four because I don't even know if I'll be using that much, so I imagine that this one-time fee isn't worth it.
