The Chief KITMTTU522 Thinstall Tilt Mounting Kit provides you with the Thinstall MTTU Fixed Mount and the PAC522 Flat Panel Pre-Wire In-Wall Box. The kit mounts 26 to 47" flat panel displays, allowing for fingertip tilt of 12deg. and ultra-thin depth. The included In-Wall Box helps to keep things organized by providing a recessed space for excess cabling and surge protectors, or power conditioners. Like other Chief mounting systems, the KITMTTU522 installs quickly and Chief's GlideLock feature provides tool-free latching.
