Any suggestions on how to mount a heavy mirror to a wall where it
might get knocked?

The mirror weighs about 17kg and is to be mounted half way up a
stairwell at waist height where the stairs turn 180 degrees.

Naturally, being so heavy makes it unlikely that anything would move
it accidentally but I am concerned about the possibility that if it
were to be dislodged, especially from being part way up a flight of
stairs, it could cause serious injury.

Oh, and because of where it is to be mounted it will be viewable
from above and below so the fixings ideally would be hidden behind
the mirror.

An impossible ask or is there a good solution?




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?

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.


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.
