Hanging a heavy mirror where it might get knocked

Depends on backing/frame but possibly something like

And I'd not expect to get all the brackets in the right place first time :(

Some sort of keyhole plate hanger?

Eg.

Is it in a wooden frame or does it have backing?

If so what about a metal version of a French Cleat?

I was going to ask that question and make the same suggestion. Also, do you want it flat to the wall, or is it a more traditional mirror hung like a painting on screw eyes and chain or wire, so that it tilts slightly inwards?

Thanks. They look good.

Agreed!

It would need to be flat to the wall.

The metal French cleats look strong but on their own would allow the mirror to be moved sideways so I might combine them with the brackets mentioned by Robin.

They also look as though you could accidentally get a foot or knee under the mirror and push it up and off the wall. So some sort of bracket limiting upward movement would be desirable.

With that weight, friction will mean it will not readily move sideways, and with a "full width" fitting it would have to move a long way before it tilts. The degree of overlap means you would have to give it a substantial impact from below to dislodge it.

If you are that worried about it moving, go for standard T shaped fixing plates and live with the visibility of two above and one (or two) below.
