I need some metal mounting brackets and I'm struggling to even know what to call them. They look like closed bar holders (like these), except I need them for small pieces. I can be somewhat flexible, but ideally the brackets would be about 3/8" deep and 2" across. I just spent an hour searching for different terms and haven't come up with anything.
Is there such a thing? What's it called? Where can I buy them? Thanks!zinc-plated-hillman-barn-door-hardware-851902-0-64_145.jpg
