This bracket fits for Panasonic TH 37PV71F, 37 inch, plasma; 23 kg. This has the unusual VESA_Mass: 660 X 320. Contrary another recession here the enclosed anchors were sufficient and with a little skill, the holder could align well. It is very stable and the extendable arm is working fine. Thanks to the expert advice of telfonischen company Ricoo it quickly became clear that the weight of Panasonic with 23 kg of is far enough that it must be a double-arm mount (as the R28 Xl). A single-arm mount is completely sufficient and is smoother than a double-armed. In addition, it is also more than the double-armed model with schwenkabr 180 degrees. The price-performance ratio is very good. We would buy the mount again.
