Question: Will this fit over a standard 120V single gang box and be flush to the wall?  I ran my HDMI and Coax cables into standard new work junction boxes
Document: This works perfectly for HDMI and all audio/video cables. But power cords that have the ground plug will not fit. I had to trim the faceplate about 1/16th inch on each side to get my tv and dish power cords through. It looks good and keeps out any drafts that might be inside the wall, but if you want this for power cords, be ready to trim the thing.
Fits on a standard existing outlet. Looks a lot better than having 5 cables through a hole in the wall.
I rate it 3 stars b/c its fine if you have a thin cable. However, I wanted to run a cable from a little refrigerator that I installed in the pantry to our outlet in the kitchen, and the head of the cable was too big (didnt fit). I ended up just taking a standard plate and making a hole on it.
I just did a custom job on smart tv, where I hid all the cables inside the walls, and then patched the walls back up. I needed these for the RCA and HDMI cables. Perfect.
I was unable to find this style in the big box stores. Makes wall mounted tv installation look neat and professional. Good quality product.
I purchased the In-Wall Cable Access Port from Amazon, because I had shopped the item at my local Big Box hardware store, and could find the item only in a package set, for about $55.00. This set contained several things I had no use for. I decided to see if it just may happen to be available at Amazon.com, and BINGO! There it was, and at a great price too.
Bought a bunch of these for my house to run hdmi and power through the wall and they work very well. thanks a lot
This wallplate is perfect for running some wires back through the wall behind my TV, to the router/cable box setup back there. Easy to install.
Provided a clean wall presence for audio cables. I recommend it if you're looking for a white outlet to match your wall switches.
I had to run a TV power cable inside a wall and I wanted to bring it through without cutting it. I didn't want to use the big pass-through tunnel that can accomodate lots of cables for just this one cable. This really looks dapper. It was easy to install.
Answer: It should work just fine. Depending on if the face of the new work box is flush with the Sheetrock. If not, some longer bolts and a couple of nuts to use as spacers for the faceplate should be good to help make it flush.
