Most of the floating shelf brackets I've seen appear to be tailored for fastening to studs. I need a bracket for a 60"L x 8"D x 5 1/2" H cedar fireplace mantle. The bracket will be mounted in a brick mortar bead. The Studlock bracket looks very nice but I can't see how this would work for my application due to the mounting holes being on the top and bottom edge of the bracket rather than centered. I did find this bracket https://www.diyhairpinlegs.com/produ...40695207526587 that looks pretty good but wondered if anyone else has suggestions for mortar mounted brackets.
