Arlington's recessed two and three-gang TV Box™ for new or old work allow you to mount LCD and plasma TVs, and other system components, flush against the wall.
These combo boxes offer power and low-voltage for Class 2 wiring of satellite or cable TV, speakers, etc. Secure installation, good looks, and a great finish.
Mounting wings tighten against the wallboard to hold the box firmly in place. There's no wobble once the box is installed. In new construction, box mounts to stud for extra-secure support.
