Thanks for the discussion. I am enjoying the revisit to college physics!
Bjex- I have seen this Natural Handyman website page before. The page does not discuss the Toggler/Hilti style toggle bolts. Would you (and others) mind taking a look at the Toggler snaptoggle page and let me know what you think about these specifically? If I do go into dry wall only, these are the only bolts I will use.http://toggler.com/products/snaptoggle/overview.php
The design is definitely different compared to the traditional dry wall anchors.
Now-- brace yourselves-- and please don't yell at me or belittle these stores...
I spoke with two local well respected Not-Big-Box HT stores/installers in my area, and a general contractor.
- One installer supported using the Hilti bolts, but cautioned about tilting the tv too much. He would use 6 of them for the 40" TV.
- The other store's installer wasn't there, but the person I spoke with thought that they did use some version of a toggle bolt if needed. I haven't heard back from the installer yet.
- The general contractor who had no reservations using these particular bolts for hanging the TV. He suggested 6-8 bolts.
- Samsung service wouldn't commit either way, even though they include the Toggler/Hilti bolts in their Ultra Slim Mount package.
Some specifics on my project, since you guys have been suggesting ideas for me...
I am mounting this tv in my exercise room. It is going on a section of wall that is 9 ft tall and 40" wide. The wall was framed originally with two cubbies for the old tube tv's (one facing the exercise room and one facing into the bathroom). I had a contractor wall up the exercise room side and open the bathroom side to make a vanity area. That's why this section of wall has no studs in the middle. I didn't have the foresight to have studs installed to hang a tv cuz, at the time, we decided to ceiling mount a TV in the opposite corner.
Now, there are horizontal studs in that wall at not quite the right places. It appears that there is a horizontal stud at about 8-8.5' up. So, I purchased a Sanus mount that screws in at the top of the mount. Hopefully, this will allow the TV to hang down more and the tv won't be too high up. I can tilt the tv up to 10 deg. I'm going to get a Samsung LED that's 27lbs to keep the weight down. I'm going to get rid of my current Sony LCD that weighs 48lbs (anyone interested in that and/or an Omnimount ceiling mount?).
I'm also installing a 26" Samsung LED underneath the 40". This TV only weighs 12lbs and I'm not tilting it. I have no problems using the 2-4 Snaptoggles to mount this into dry wall only. I currently have a framed print that weighs 11 lbs hanging on this wall on only
a screw and it hasn't budged in 3 years.
An aside-- anyone have experiences with HDMI splitters?
I appreciate Giz's suggestion of mounting a board as the support (my dad did that in my house growing up for our towel bars in the bathrooms). Aesthetically, it won't fly with the wife.
I can cut the wall open and install some studs, but patching and re-texturing will be difficult. The texture is such that it can only be done by hand- not by spray bottle- and I don't know how to do it.
Thanks again to everyone for your suggestions. This install will (hopefully) occur this weekend. I'll let you know how it goes. Sorry for the huge post.
Oh, I live in a very dry climate with no earthquakes.
