I would rather ask and do it right the first time (there’s not a lot of room for error on this project). It seems I can save several hundred dollars by doing this myself. Plus, I don’t think this is my last TV that will need mounting.
I upgraded my 6 year old, 42” Samsung plasma to a Panasonic TH-46pz850u 46” plasma which is 46.5” W x 29.6” H x 4.1” deep and 84 lbs. Instead of buying a new Salamander (very low and expensive) stand, I want to mount the TV to the back wall instead, and “float it” toward the top of the cubby hole (with the option to have it recessed or flush). The components will go at the bottom.
It’s going into a built-in bookcase section that is 47” W x 47” H x 29.5” Deep. I will likely use the mount fully extended at all times. Needless to say, final spacing is pretty important. I think the mount needs to go in the middle (at the correct height).
After reading some other threads, I am thinking I will probably go with the Sanus VMDD26.
- Dual cantilever. Rated to hold up to 175 lbs. (850 is 84 lbs)
- It extends to 25.75 inches. 25.75 plus 4 inches for the 850 is 29.75 … perfect.
- It does the various Tilt, Swivel, Pan, and Roll (to level bezel) that I want.
- You have flexibility with stud spacing.
- Lots of satisfied customers using it with big heavy plasmas (including pro-installers).
- People say it’s easy to mount it (I’m going to need all the help I can get).
- Probably overkill for a 46” but I think the extra money is well spent for the insurance.
Like the whole structure, the back is painted sheetrock, built like a conventional wall. I have the pre-sheetrock pictures we took as we built the house (I will use a stud finder and finishing nail when the time comes). It looks like ... 3 evenly spaced 2x4s (the standard 16” on-center). The first hurdle I notice is that the middle stud is basically in the middle of the cubby (with the other 2 studs about 16" to each side). The mounting plate for the Sanus is 26” wide. I would rather not do extra work, but it looks like this requires external framing to go in first. I was thinking (2) 45” 2x10’s lag bolted to the back wall first? ... (horizontally and at the proper height)
Did I select a good mount? Does it sound like I need the external framing? Am I on the right track?
Here is a pic of what it looks like now, before I start (still with the old 42" Samsung).
