Question: Can I install it 45° to the right, to allow the opening for wires to drop in from above?
Document: A neat clean solution for all of those cords. The only problem is that that the area where the wires come through is wide open so you wouldn't want to put this where you don't want an air gap. A slit rubber gasket across the opening would help.
I ran the following wires through the opening with room to spare:- HDMI x2- Optical- Component A/V- IR Extender (1/8&#34; style cabling, similar to what is used for headphones)- Wii sensor bar extender cable- 16 gauge speaker wireI would recommend changing the outlet with a Leviton surge protected outlet (or similar product) if you do not have another option for surge protection, that is, an option that won't leave your setup looking like crap.
This was easy to install and makes hiding cables from your tv to your equipment much easier. I placed this right behind my tv next to the tv bracket. Quality is good and the price is much cheaper than if you bought the same product from depot.
box is as advertised, box is a little bigger than expected, approx 7 1/2&#34; x 7 1/2&#34;. you will need a good opening between studs to install it correctly. fit all cables through opening that i needed to (3 HDMI and one Large Component Cable).
Holds wires. Easy to install. The only comment I would make is, make sure the plug side is far enough away from a wall stud to fit. Since the box is at a 45 degree angle, you need to consider that in your placement. Not a biggie.
This was perfect to hide the wires from my TV, the unit is pretty big so I would only used it for 50&#34; TVs or larger, but the countersunk outlet was the key selling point for me. It was super easy to install, and looks great. I am not a handy man at all, but it was simple and now that room looks awesome.
I had been looking around for some thing like this so that I could get all the ugly wires behind the wall into a nice,neat little package. This worked well,I have the power and all associated HDMI cables inside the wall and hidden behind the TV. It was very easy to install and everything looks great.
I hung a 32" flat screen on a kitchen wall. I bought the receptacle to solve problems with small children fooling with the wires. Of course that was solved but in addition, the TV install now looks so tidy and professional without those cords hanging down. Great idea and the recess allows the screen to fit nice and close to the wall.
This is a good product, it did what I needed it to do! As others have said, the tabs on back are weak, don't over tighten and you'll be ok!Well packaged and sent right away!
I used the mount found here:  http://www.amazon.com/gp/product/B00AY98USQ/ref=cm_cr_ryp_prd_ttl_sol_15 . This mount overlaps the edges of the recessed plug, but that was no issue. I did not have need of the cable run, but was able to tuck away excess power cable in the opening. If this is installed properly and cleanly, it actually looks very good.
Answer: It makes no difference how you install it but if you install it so the cables are dropped from above make sure the electrical is on top too, if not the cables will have a kink\bend because as you can see the edge of the box will cut it to it.
