View Full Version : Wall mounting with studs oriented the wide way.

I have a 42" Panasonic coming in a week and have been looking into wall mounting it. The problem is the wall I want to mount it to has a pocket door inside it, so the studs are oriented 90 degrees from standard. Is there going to be enough thread engagement for the wall mount with the studs oriented this way? Has anyone had to mount a TV on a wall like this before.

do you know how thick the studs are?

The studs are standard studs, so 1.50".

so standard 2x4s ... gotcha

what type of mount are you using?
if it is mount like this> LINK (http://www.monoprice.com/products/product.asp?c_id=108&cp_id=10828&cs_id=1082801&p_id=3899&seq=1&format=2) and you are able to hit all 4 points with lags, I think you will be fine

If it is a mount with a smaller mounting footprint to the wall, and has an extending arm, I probably wouldn't risk it.

42" panel only weighs 60-70 lbs so it isn't a ton of weight

The wide mount is the type I was looking at. So I will have 4 studs to mount to spaced out on 16" centers.

BTW any advantage to getting a more expensive wall mount? Is there really a difference between those cheap $25 mounts and the more expensive up to $200 name brand ones?

any idea the length of the screws that come with the mount?
what does the mfr have ot say on the matter?

I'm a carpentry contractor, and I also have a 42" Panny wall mounted. Trust me, if you can hit 4 of those studs you are MORE than secure, even with them being on the flat. Just make sure to drill smaller pilot holes for the screws so the studs don't split.
I wouldn't hesitate to mount it on 2, with four large mounting screws.;)

Okay, you are not going to hit 4 studs unless they are 12" on center, or a 36" span. Four normally spaced members at 16" on center would be 48". But, 3 studs will be relatively strong enough if the mount itself has the ability to not deflect with the weight of the panel. Studs turned onto their sides have little in the way of resistance to deflection, so the mount itself needs to counteract that. And, you would not want a lag longer than 1-3/4" into that framing member, or you could penetrate the member, and scratch the door in the pocket.

Um, too small a pilot hole will make it more likely to split the stud... like not drilling a pilot hole at all...

Sheeeesh.,.,.,no kidding.,.,what did I say,. drill a smaller hole than the screws...not a 1/16" hole for a 1/2 inch screw obviously.
And a smaller hole will make it MORE likely to split than no hole at all????
Sorry pal....ur wrong. It may split...but it IS NOT more likely!
Just a little common sense is all that is needed here...:cool:

Anyweay, I STILL would hang my 42" Panny on two flat studs flatways, (with proper pilot holes drilled!), even if only on two without a worry on my mind.
Y'all underestimate the strength of 2X4 lumber with sheetrock attached, even flatways. Now, I wouldn't attach my 58" that way, but a 42" no problem.....
Oh well, what do I know....only been building & remodeling homes for 38 years...:p

....Oh well, what do I know....only been building & remodeling homes for 38 years...:p yeah, but in here you're building with words, and it did read like you were saying 'drill smaller holes than you would if the studs were orientated normally...', though with your explanation it's clear what you meant.

BUT, just to understand, when you say QUOTE "Y'all underestimate the strength of 2X4 lumber with sheetrock attached, even flatways" UNQUOTE

so the wallboard is attached to the flatways studs on that side of the wall ? or am i not understanding and further (you can tell i haven't the knowledge), just for curiosity, are studs placed flatways inherently less strong ? would there be some additional studs placed outside the pocket area that the OP could take advantage of?

thanks for your expertise

Yes, you only have 1-1/2" of strength rather than the full 3-1/2"...besides the wood's grain differences also. Grab a 2x4 and see how easily it bends if you push on the flat side...now try to bend it pushing on the side! If it's an exterior wall, unless the OP is finding lathe on studs from a plaster wall, I highly doubt the construction is studs on the flat. It would only be that way for blocking of some sort.

No, what you said was "drill a smaller hole FOR the screws" (emphasis added)... could easily be misconstrued... in reality, the diameter of the pilot hole should be the same regardless of the orientation of the studs...
And a smaller hole will make it MORE likely to split than no hole at all????
Not what I meant. Obviuosly, an undersized hole is better than no hole.
Just a little common sense is all that is needed here...:cool:
Likewise, I'm sure.

You guy's are nuts. The flat side will be more then enough. 2 or 3 studs would do on the flat side. How much weight do we all think we are talking about here? 80-100lbs?

Whoops I mis-typed. I will only be hitting 2 studs I think(maybe 3 I won't have the mount to measure until tonight). I meant 4 lags in 2 studs. I went out and bought some 5/16 X 2.00LG lags so I can mount it without hitting the pocket door. I pushed on the wall and with the drywall on it is very stiff even with the studs on the flat. I am planning on predrilling with a bit the size of the minor diameter of the lags and using soap on them as well to make sure I don't split the studs. I'm pretty excited, this is my first TV over 27", can't wait to watch the Brewers in HD this spring!

Even with the 2 studs on the flat, It really should be more then adequate. So you bought slightly shorter lag bolts? 4 bolts in 2 studs will be fine even on the flat side. I would'nt worry about that. The Tv doesnt weigh THAT much.

Jim Hef
12-11-08, 02:30 PM
Agreed, that combination should be fine...the mount itself will spread the weight. Get some washers for those lags just to be sure that the 2" length doesn't penetrate the stud and rub against that pocket door.

Exactly my point. And I am sorry if I was unclear on my explanation of pilot holes, etc.:cool: The FLATWAY studs will only have more deflection from weight hanging from them.
But, not the small weight distributed over the area we are talking here, and with at least 4 attachment points....

LMAO, so...in summation of all this....YES..hang the damn thing on those flat studs!!!
Just be sure the mounting screws are not too long as to go through into the pocket door area!!! Ouch,.....
"Honey..the pocket door is stuck!!??"

Haha

What are you doing with the wires and cables? A pocket door might (will ) be a problem if you are going to bury them in the wall.

There is actually about 4" between the face of the drywall and the pocket door. The house is 100+ years old and the door is original, so its not like one of those retrofit pocket doors that sit in a standard thickness wall. I am mounting a receptacle up behind the TV and will be running an HDMI and set of component cables through the wall. As long as I pull them fairly tight at the bottom I don't think I will have to worry about catching them.

The important thing to remember here is that you got the right tv. Panasonic Plasma.

What model? TH-42PX80U? Prob one of the best deals out there.
