Does not require double side tape, holds the touchscreen firmly. Easy installation. Easy to remove screen if needed, just slide off the lid. For initial installation requires to open touchscreen, take off the battery and unplug the wire temporarily to hook it through the hole. But its quite easy (see photos). As well as removing the stand bracket, that you won't need.

Couldn't find any wall mounts for xfinity touchscreen. Touchscreen itself is designed to only stand on the table, which is far from convenient. Also the shape of the touchscreen is quite tricky, but was able to measure it roughly. Turned to fit pretty well. The only other wallmount i found uses sticky tape to hold...

As always, use at your own risk! :)
