Integrate your Sonos Arc or Arc Ultra with your wall-mounted TV The Sanus WSSATM1-B2 attaches directly to your TV wall mount so you can place your Sonos Arc or Arc Ultra sound bar directly below your mounted TV. The bracket can extend your bar up to 5" inches from the wall. This allows easy access to back-panel connections. And it provides clearance for your Sonos bar's up-firing Dolby Atmos speakers, moving them out from under your TV. Simple setup You can adjust the height of your mounted sound bar up to 15", so you can use the bracket with TVs up to 90". Easy-release latches let you make adjustments without using tools. The bracket connects directly to your wall mount, so the sound bar will always remain in the same plane as your TV, no matter how you swivel or tilt it. You can use the bracket with fixed, swivel, or full-motion mounts. What's in the Box: 1. Vertical bracket 2. Horizontal bracket 3. Extension arm 4. Four M5x8mm screws 5. Four M5x25mm screws 6.
