You mean like this Lizzie?
Went to Lowes and bought two of these. They're rated at 800 pounds I think the package says. As you can see in the picture I have this one installed on the stud next to the window. The other wall is in the stud next to the closet. These are double studs, there is a header and footer for the window in the one next to it. I've had the sheetrock off the wall before so know the condition of them and that they're full length in the wall. Sure, I'm really only into one stud but it's nailed to the next one. Frankly, if you'd seen the size of the TV I had hanging from a single stud in the wall you wouldn't worry much about hanging the average human. I'm just a little shy of double that weight by the way.
