The Chief PIWRF2000B is a preassembled swing arm that fits flush inside the wall with a low-profile finish. It was designed for 42-65” flat panel displays up to 200lbs and can be installed without having to cut studs or having to retrofit existing wall structures. This device allows users to have more flexibility with their viewing angles as well as fingertip tilt access. This piece requires an interface bracket (sold separately) for your flat panel TV or monitor.
