Question: Will this work with double-thick drywall (for soundproofing)?
Document: I was surprised at the size (it is large), since I did not pay much attention to it when ordering. Installation is easy but you need to install it away from a stud the way the locking ears work. Nicely made, outlet is good, construction and finish are great.
Easy to install, holds securely to the wall, thick durable plastic that will hold up to the low demand on the product. It is fairly large which might make it difficult to install some TV mounts around it, however it did fit just barely inside of the mount I was using.
I did use my own outlet, the one that comes with it will work fine, but it has that plastic inside the plug that you have to fight to plug anything into it. I've already delt with something of the sort didn't feel the need to do it here. I will order and use these throughout the house on all of my flatscreens, I recommend this product!
Very easy to install. This version had the upgraded metal tabs for securing to the drywall. Came with a faulty outlet which was replaced the next day after contacting Amazon. Glad I found this product.
This product would be great if the plastic tabs that hold the box against the drywall were stronger. One broke while installing it, seems others have had this issue also. Sent it back to Amazon for credit
I have read other reviews of this product which suggest it has plastic clips to attach to the drywall. The unit I received had metal clips and screws. I installed it and then uninstalled it to change my setup. I am using this in a ceiling for a projector.
I used this for installing a TV in the bathroom. It was an easy install, took a few minutes, used the included template and cut the hole in the drywall, wired the outlet and ran the HDMI cable through the hole. Looks clean, and is recessed and hidden.
I chickened out when I actually saw the size of this thing because I didn't want to make that big a hole in the wall. I'm mounting a tv on a brick wall, so holes are a little more permanent than a drywall wall. Just beware that it's a hefty box.
This enclosure is perfect for a rear or in particular a side wall installation e.g. a drywall frame out for a gas fireplace. Mount it on the side and the recessed design makes the installation clean and only the cables to the TV protrude out. The AC receptical is hidden and comes already installed (except for the romex cable).
I wanted to mount a TV on the wall of by bedroom. I found this and decided to give it a try. It was much easier than I thought it would be. I measured for the mount and then determined where to locate the recessed plug. I used the template provided to draw the cutting path and a drywall saw to cut the hole.
Answer: Yes, it will still fit within the wall as your studs are more than likely providing the same interior clearance as a standard wall.  The clips you tighten to secure the box to the wall are going to be your only issue, and that will depend on how thick the drywall is.  Worst case scenario, you can go to a hardware store and purchase longer screws, then you may just need to notch the inside of the drywall to provide clearance for the electric box.One thing to keep in mind, as the port for the cables stays open, this will negate much of the soundproofing benefit you are getting from the doubled-up drywall.
