Home / TV Mount Question

I would be a little concerned with extending it that far out… What are the dimensions of the plate that will be mounted, and how many mounting bolts?

I have to extend it at least 25" (and will probably leave it extended about 30") most of the time. The mounting plate is 27" x 10" and I was going to use 4-6 bolts.

Also, run a stud detector just in case. Just make sure you do the obligatory joke where you point it at yourself, have it go off, smile and say “there it is…”

Oh, that's been done.

Agreed. The further you pull out the TV, the more force gets put on the bolts (it acts as a lever).

If you get into the habit of pushing the TV in and out, the setup will deteriorate further (friction between the bolts and the 3/4 inch wood and drywall behind).

Will the TV cover most / all of the cubby? If so, you can add some additional wood to reinforce the 3/4 wood, and fix it to the rest of the built-in structure.

Yes (and to @Loki too), that is a good idea. The TV will "hide" the back of the cubby so I may look at mounting a 1/2" plywood or something to the existing wood back panel for additional support. Then mounting the TV mount plate to the plywood/wood which will be 1.25" in width at that point.

Leave the legs on the tv and just place it on a horizontal surface.

is the second best solution.

Best solution is to just watch TV on smaller screens. You'll love the portability and appreciate the energy savings soon enough.

Haha that won't work. Maybe I'll send a picture later but trust me when I say the viewing angle and size of the cubby aren't realistic for those sitting in the room to see.

3/4" backing with the right toggle bolts and you could stand on a platform 24" out.

This is a review (test) of drywall anchors.

Informative, though.

Go with the toggle and NOT the supposed stud anchors. Plastic Drywall anchors work great, the ones built for wood? Not so much…

So I remember when you posted this before. Was really insightful! I'll keep it in mind for sure.

Alright so above is what I’m talking about. Note the existing mount from the previous TV already installed, please ignore.

So the wood panel back you see is 3/4” wood. I don’t know what type of wood but it seems relatively solid and seems to run the length of the whole shelves.

Silly question but… if I mounted some plywood on the front of this wood back panel with some lag screws, then mounted the TV mount through the plywood then back panel wood with the toggle screws, would that help? Or would the plywood do nothing since it’s on the front (not back) of the back panel wood?

[89th]

Alright not that anyone cares, but I did some examination... looks like it's likely a walnut veneer on top of 3/4" ply, and that there are studs back there but they are 1.25" from the wood (aka a total of 2" from surface to stud surface) so I should be able to get some long ass screws to get the mount into the studs directly.

Looks like birch or cherry to me, but what do I know.

All plywood is veneer, by definition. It's the "good" side that determines value, etc. Walnut is, of course pricey.

You could be right, mine was a quick guess.

Birch is by far the most common in the trades.

Yep - the bolts that came with my mount were about 3 inches. I'm guessing you could probably get something 4 inches and that'd be super strong.

If you can anchor it into a stud you will be fine, but as Xenon says, use the longest screw you can find (but not longer than the 2x4 is wide) and the thickest one that will fit the mounting.

Adding more plywood to the back would be fine only if it or the existing back anchors to the frame. But the studs are the way to go if you can.

[89th]

Thanks @Mik

@xenon - Indeed the ones that came with this mount were 3" but I already purchased 4" so I'll use those. Next step... drill a pilot hole for them and (hopefully) hit studs. I also have two snap-toggle bolts I'm also going to add to the center of the mount since that part is definitely not on studs.

[LuFins Dad]

I think you should be good…

Alright the TV is up and extended away from the wall... nothing seems to have fallen yet. Ultimately the snap toggle screws I used didn't work because of something behind the wall (insulation? I have no idea). I also had to cut out a little hole for some audio wires. Finally, the main screws didn't work so I had to use alternate screws that I (think?) went into studs or at least another sheet of plywood. Man, I just wish I had a normal drywall/stud wall to work with next time.....
