Has anyone mounted a 67.5lb Plasma to Metal Studs??

Hello all, need your advice.

I have a Samsung PN59D6500, and I've been wanting to mount it. I received this mount as an early christmas present:

http://www.peerlessmounts.com/dyn/Pr...2/u/t/av/13966

I have metal studs. The mount says you must use their metal stud mounting kit, which are just toggle bolts, so I picked up the exact same size and type from home depot. The peerless mount needs to be mounted into drywall that is at least a half inch thick [check] and metal studs 26 gauge or heavier [unsure]

The wall I am mounting the tv to is not load bearing so I'd imagine its not 26 gauge (there is a planter shelf on top of the wall) but the wall seperates the living room from the garage, so its possible its reinforced with thicker gauged studs. Studs are 24" apart.

I've been reading mixed reviews regarding the security of mounting a tv to metal studs. First of all, my TV doesn't seem that heavy (67.5lbs according to samsung) , but I don't want to home home one day and my tv be sitting broken on my floor. Some people say the toggle bolts will hold just fine no matter the gauge, since there will be 2 toggles in each stud, and its a slim mount. Others say I need to take off the drywall and reinforce, or mount plywood to the wall and mount on top of that, which I don't think I'm interested in doing.

I figured I would direct my question to you fine folks, as I'm sure some of you have first hand knowledge and experience with this. What does everyone here think? I appreciate the feedback

No answers, eh? The silence is telling me that I probably shouldn't go direct into the metal studs with toggle bolts.. This may be a pretty sensitive subject I guess.

Does anyone know of any instructional videos that show the best way to mount MDF or how to remove the drywall and brace the metal studs with wood?

If this was my TV in my house I wouldn't dare try this without adding some wood support to the metal studs. I would remove the drywall in that area from floor to ceiling and insert wood studs. I'd probably even over kill it and put twice as many studs as you need, and while its open, cross brace it at the height you want the mount so you can basically put the mount anywhere without using a stud finder. This way you can also run all you wires and cords and easily install a receptacle before putting the drywall back up. We are talking a one day job for you and a buddy. Then tape, plaster, sand, prime and paint and you are ready to go. This way in the future if you decide you would also like a full motion mount or a bigger and heavier TV you are also good to go.

The mere thought of someone hanging a TV to metal studs alone makes me squeemish. I'm not saying it couldn't work, but it is definitely no substitute for wood studs. I sleep good at night knowing both my 54 and 60 inch plasmas are both screwed into 2 x 6 studs with 4 (3 1/2 inch) lag bolts each! They aren't going anywhere.

Just my 2 cents.

I really don't have the time/knowledge/budget to remove my drywall and install studs floor to ceiling. Doesn't seem like a task that is hard to learn, but factoring in time/budget its just not feasible for me. I really appreciate the feedback.

I have talked to several people as well as some Professional installation companies , and they all say I can get by with reinforcing on the outside of my wall with MDF or plywood. Not one professional I have talked to has recommended togglebolts directly into the studs, even 26gauge or higher. They all have the same on the fence answer.. That it could work, but its an expensive risk. I have yet to find anyone that has taken this risk to see if they've had a good result.

So I'm going to try the plywood reinforcement. I'm going to cut a peice about 30"x20", and secure it to the two studs I can span with as many bolts as I can.

People say Lag bolts should work just fine into these studs, but everyone's worry with mounting directly to metal studs with Toggle bolts is the bolts could work themselves out eventually.. That being said, wouldn't Lag bolts have more of a chance to work their way out since there is no 'anchor' on the other side of the bolt once its into the stud? I know it will be into the plywood, but the lag will be securing the plywood to the stud, which I think could possibly rip out of the stud and send the plywood, mount and tv down to the ground. I was thinking about coming up with a way to toggle the plywood on, seems safer to me in theory unless someone can give me peace of mind with the Lags. I will probably add tons of additional support into the plywood through the drywall just to curb my paranoia ;D

Has anyone tried this method at least? Any additional tips to offer?

You can use woods screws, pre-drill your holes all the way through the wood and the metal stud. Wood screws allow you to get alot more than lag bolts / toggle bolts / etc. I had to put a 2x6 in the roof of my garage, into metal studs to hold my Jeep top hoist. My Jeep top weighs 140lbs and I spanned 5 metal studs with 3 screws in each stud. Then drilled a 5/8" hole for the 3/4" lag eye bolt. I made sure that the lag also was drilled and went completely through the metal stud. Trick is to pre-drill COMPLETELY through the metal stud (not just your wood) and to have your drill on slow to not strip the hole when screwing in screws.

I found a long mount that allowed three metal studs to be caught - 32 inches. Then these anchors, http://www.hilti.com/holcom/page/mod...&nodeId=-11623 found them at HD.

Been up for three years, so I think I'm okay.

You are probably fine.

That said, the idiots who built my house probably felt the way they installed the bathroom mirror was fine. And the first 12 years or so of it staying up "vindicated" them. The day it fell off and nearly crushed someone in my house however provided ample evidence it was done wrong all those years ago.

I relate this story not to suggest your mount is any way flawed, just to point out that 3 years is not necessarily compelling evidence that it's done right. Had the mirror in my bathroom been installed properly, it would still be on the wall; it wouldn't have landed on the floor.

In doing a quick search, I could not find any supplier that had metal studs thinner than 26 gauge. In fact, the thinnest I found was 25 gauge. So, you are probably safe with the mount requirements.
