The SB-39 is made from high quality steel to hold sound bars up to 15kg/33lbs. It is suitable for most SONOS, SONY & VIZIO soundbars, and, can be easily attached to TV wall brackets or TVs on the stands directly instead of mounting to wall and leaving ugly screw marks. It gives a clean and neat look with your sound bar sitting above or below the TV. The mount is ideal for hanging on a corner or on an articulating mount where the sound can face the same direction with the TV to make perfect auditory and visual experience. The sound bar brackets can be mounting with standard VESA 200X100 to 600X400.
