Just get a framed mirror and hang it like a picture.

I don't think so. I've seen metal rails to finish the edges, but I'm pretty sure they were glued on too. A mirror that size needs to be secured. Maybe hang a framed one instead? or two smaller ones?

Not recommending this seller, just showing the hardware.

me too -- we have a big one with clips. I try not to think about it, but they've been there for decades.

There's nothing wrong with clips, I have one that's bigger than yours hanging like that. Much easier to redo when you want too.

Just removed a large frameless ceiling-high mirror. It had a kind of track at the bottom that was resting on the vanity, plus the clips on top. It was secure for 25+ years. Three other in the house that are even bigger.

We used these round chrome "hangers" for 36x36 mirrors. I think they look really sharp. Reviewers described using with larger mirrors.

I have large mirrors in my exercise room. They are held at the bottom by a long J strip that has been fastened to studs. The tops are held in place by mirror clips that have been fastened with wall anchors. The reason for using the J strip on the bottom is that the width of the mirrors doesn't correspond in any easy way with the wall studs.

The J-strip/track methods feel more secure to me somehow, although I've never had a problem with others. They CAN, however, end up indirectly damaging the mirror. Maybe it's not the case with new mirrors, but with old ones, when water or Windex would get into those tracks, it would sometimes creep up the back and mess up the silvering. This seems to happen more in kids' bathrooms for some reason. Hmmmmm...

If the back of the mirror is lacquered, the silver will not be damaged.
