Question: Can this work on a tv mounted to a patio with a swivel arm?
Document: Purchased this for work. I have a small flat screen in our customer waiting area. The TV is mounted on the wall with a arm. I was able to take out 2 screws holding the backing plate to the tv, insert the secuity tubes and existing screws,  install the security, metal covers in the tubes. I threaded one end of the cable through the 2 opening in the tubes, and around the arm.
placed this on my outdoor tv for added security. Easy to install and very secure! i have it drilled and mounted into the brick wall.
I have a 37" tv mounted in a three season porch and wanted to protect it from an easy swipe. I looked at the Kensington locks but they didn't seem to be that secure and then I found this kit. After reading the other reviews I thought I would try it and am happy I did. It was much less expensive than the Kensington lock, and it seems pretty durable.
We have a large TV in our library to play Wii games for physical activity and fun. Recently, we had a break-in and the thieves stole the TV by breaking the arm on the mount. We purchased this device and are hopeful that it will allow us to keep our TV should thieves return. The reviews indicate it will preserve our investment!
Super easy to install by myself. TV is outside and was already hooked up so all I had to do was remove one screw at a time, add the bracket that holds the cable and replace the screw. Did that for 2 of the screws in back and voila. I don't believe they offer different lengths, but would be a good idea especially for articulating arms. I can't open my arm the whole way because the cable is just a bit short to extend it completely - but only by a few inches.
This kit didn't work with our flat screen TV mounting. Make sure this is compatible with your TV and where you are mounting it before ordering.
Put the in a rental property. Easy install and would require some serious work to remove a set secured with this.
I was very disappointed to find that this anti theft kitdidn't work for my new 46&#34; Samsung Flat Screen.
It may seem a little crazy to lock down items in your own home, but that's what I've done after my house was broken into in the Spring. Really, though, the way I rationalized purchasing this security kit is the placement of my television--specifically, I have my 65&#34; flat screen sitting on a media stand rather than mounted on a wall.
I think this is a great anti-theft security kit, it was easy to installed and feel confident about the security of my TV. I do wish that the wire was just a little longer, but I made it work. Lenny
Answer: So long as you have a wooden stud that the device can be screwed into.  Nothing is absolutely unbreakable but it is very difficult to remove a TV attached to this device without ruining the set in the process.
