I've TRIED TO HANG a 100 pound mirror using hollow hangers. The product has to go into dry wall which makes it tuff. There are 2 very strong metal looped chains on each side that support the 100 lb. mirror when you hang it. The problem is both times the hollow hangers that expand into the dry wall (that i banged into a board in the wall won't hold the mirror. Both times the hangers would not support mirror & came out of the wall. Does anyone know of a product that is secure to hang a 100 lb mirror. Basically it's dry wall you need to insert the anchors into except for the boards that are in the wall. I live near a Lowe's & Home Depot . My father is the one who went to the near buy hardware(lumber yard ) store but there hanger(anchors aren't strong enough to hold the mirror up Thanks

 

A 100-pound mirror must be wide enough so that you can put the fasteners into studs, isn't it? I wouldn't feel comfortable mounting this to anything but solid wood. What is the size of this mirror anyway?

 

I recently purchased a 100 lb. mirror and began measurements to hang it.
The loop hangers that came mounted to the mirror frame measure 36 inches apart.
The studs in my wall are 16 inches apart. Hence, 2x16 = 32. This leaves me with a 4 inch gap off of the closest stud in the wall.
Is there anything I can use to mount one side of it aside from a stud?

 

My mirror is currently hanging on my wall.
Get "Heavy-Duty Screw-In Anchors." These are all metal or similar substance. I found these at Lowe's in the nail section. The brand I bought are "Driller Toggle."
Just be sure you get ones that apply to the weight you require and specify "for drywall." Also, the ones with sharp tips will help a lot when driving/drilling them in.

I hope this helped ...
