Slight frankenthread...
Jerome, your post reminded me that a customer once asked me to visit her home and hang a large mirror above the fireplace mantel.
When I arrived, she thanked me for coming right away because she was having a big party in a couple of days. The fireplace mantel was 6 ft. above the floor and the mirror was to hang on the 12-ft. tall sheetrock wall above that, between two windows. The top of it would have been more than 13 ft. above the floor.
Then she showed me the mirror and I realized that it was for floor-standing only, about 40" x 72". It even had a large label on the back saying "DO NOT HANG THIS MIRROR".
She wanted me to hang it anyway. I declined and told her that it would be dangerous to hang that mirror, especially high on a wall without reinforcement. She apparently thought I was making excuses and just wasn't able to do the job. When she asked if I knew anyone else who would hang it for her, I suggested she first call her homeowners insurance agent and ask if her coverage included liability for injury or death from flying glass.
Perhaps she eventually found some handyman to hang that mirror, but only a fool would do it.
