I have a very heavy mirror like the author of the other "Hanging a very Heavy Mirror" thread- but my situation is somewhat different. I live in a beach community in an apartment that was built in 1957. I need to hang a rather heavy mirror(40-60lbs). The area of the wall onto which I need to hang the mirror also houses a sliding door. As a result, I don't have normal studs. What I DO have are 1x4's running horizontally and could probably utilize 2 of them- one higher and one lower on the mirror. The problem is that the 1x4's stop short so that I can only properly anchor the mirror on one side using the 1x4's. Is it advisable to use two of the picture hangers (one high and one low) rated for 100lbs(nail and bracket style) for one side of the mirror and then molly screws (also one high and one low) for the other side where it will only be anchored in drywall?

 

Go to a harware store and some toggle bolts or plastic anchor. they work great when you dont have a solid place for a screw.

 

i wouldn't trust anything but studs for a 40-60 pound anything.

by sliding door, do you mean pocket door???
