The item is specifically designed for inner and outer corner installations. Its two independent wall plates can be mounted to adjacent walls, allowing TVs up to 125 pounds to be safely positioned within a corner. Alternatively, turning the wall plates inwards allows for mounting to an outer edge, column or pillar. Depending on screen size and the distance between the wall plates, the articulating arms offer up to 40° of swivel in either direction. Further, improve line-of-sight and reduce glare by tilting your TV 15° forward or 3° backward. This product also includes cable management clips and wall plate covers to ensure a professional looking setup.
