Flush-mounted / installation frame for 14" inch tablet (142997) Please keep in mind that the speakers and microphones are located on the back of the tablet and so the quality and volume of the sound options are limited as soon as the tablet is installed in a wall. The tablet is screwed to the frame via the Vesa mount and then mounted into a drywall or wooden wall. Walls are of course also possible, but are only recommended to a limited extent due to possible heat build-up. !!!Attention, the individual installation frames are Not compatible with our aluminum panels. Panels have to be built yourself and are not available individually from us. They only fit the primeone series
