  • Really nice
Did the job great. Handy an easy to usesup

  • Great!
My daughter purchased me a Fire TV, which replaced a different 43" tv. The back of the Fire tv for mounting was apx 2" bigger than my previous mount. So happy I found this "extension"...works perfect and easy to use. I would suggest having 2 people to do this if you have a larger tv!

  • Upgrading from 200X300 to 300x400 tv and this adapter worked
We purchased a new 60" TV that replaced a 50", and the mount bracket did not fit the back of the latest 60" TV. After some googling, I came up with this product as the solution. According to the specs, this adapter can support 66 lbs, which is more than enough for our new 60" TV at 38 lbs. My only criticism is that the spacers that came with the adapter were too big, but I used the ones from our old TV; with this adapter, we were not able to mount our soundbar due to the screws being too short and the directions could be better, but I figured it out. So far, so good, and the TV is still up. It's still more accessible and cheaper than installing a whole new mount in the studs leaving more holes etc. ... show more

  • Great product.
It fits perfectly on my 42"TV; the only I missed is more different sizes of spacers.

  • Scarry but it works
It gives the monitor some tilt right and left when mounted on the arm but it doesn't bother me since the monitor is huge( asus pg42uq) besides that it seems solid and a must if you want to get rid of the annoing legs of that monitor

  • Works ok - hardware needs to be better.
We used this to retrofit a 200mm x 200mm pattern to a 300mm x 300mm. It was OK, the one issue was that the screws included in the kit are not well matched to the slots of the screws. The heads of the M6 screws go right through the slots of the extenders. Easily rectified but had to take a trip to the Home Depot to get washers to make sure they don’t get pulled through. TV is on and secure in the old bracket, but not a well thought out hardware to match the slots. ... show more

  • These worked great! Did not have to buy a new tv mount.
The media could not be loaded. Really easy to install. Highly recommend you try these out before buying a whole new tv mount with a larger VESA pattern.
