I'm a couple days from mounting a large, heavy object via Monoprice mount above my fireplace. I've already secured the mounting plate, just waiting for the electrician to wire in the service (it's family, free, and I hate working on my 200A service).
The Monoprice mount seems very sturdy. I got some good long lag screws from Lowes to firm up the install and I'm very confident the TV will hold.
But what if...
My very young daughters love to sit around and play in that area and I'm not sure I'm 100% comfortable with essentially putting their lives in the China-sourced metal mount. Has anyone installed any kind of backup system in case of mount failure? I'm thinking something that drills into a stud and attaches to the TV in a secondary manor with something with a little give to it so a sudden detachment doesn't snap it - a high rated, short bungee cord of sorts.
If the TV ever did break loose I wouldn't care about damage to the TV; I'd almost welcome an excuse to upgrade. I would rather avoid any kind of major head trauma however.
