A:AnswerIt would work but I would not recommend. If you are stud mounting get a mount that will allow you to center the mount and still get 4 lag bolts in the studs otherwise you will need to drill holes in tee mount or use 1/4 inch toggle bolts not recommended for a tv that size. If you want to move the tv you will probably have to level it again.
Take a look at my review for what I ran into.
A:AnswerWhen flush to the wall our tv sticks out about 7”. They do make solid mounts that bring the tv more flush with the wall if you’re not looking for mobility
A:AnswerI'm not sure but this mount is overkill for a 32" TV. There are other choices out there that would be lower cost but provide good mounting options.
A:AnswerThe frame itself will work with a rock face structure, but I don't believe the hardware included is meant for that. This may be an issue with any mount that you purchase.
