I'm trying to mount a large sign - roughly 7.5 feet wide by 2.5 feet high - that's made of some kind of very hard plastic on a wall (drywall with wooden studs).
For a number of reasons, I don't want to drill through the sign. But it weighs roughly 60 lbs, so it can't be glued or anything: I clearly need to mount something else to the wall using screws in studs (or very strong drywall anchors).
Essentially, this makes the project a lot like hanging a frameless mirror - I need clips or clamps or something that can be sturdily mounted, that will hold this thing in place. But the mirror clips and j-mold stuff I've been able to find are all designed for thin, flat things (like a mirror). This sign is 1/2" thick.
What are my options? I'm open to corner holders, many metal clips around the perimeter, a j-mold-like solution, etc. Just can't involve putting holes through the sign itself.
(I did do a a fair bit of searching for dupes, but none of the excellent mounting posts I found seemed to address a situation like mine. If I overlooked one, point me at it, and apologies in advance.)
