The Extendable Soundbar Mount Designed for the Sonos Arc attaches directly to the wall and has the ability to extend out 5" for proper clearance of the Arc's Dolby Atmos Speakers and Mics. The extension also provides easy access to the I/O and power ports. The Extendable Soundbar Mount features 10" of wide open wall access for power and cable management, specifically compatible with the Sanus WSIWPSB1-W1 In-Wall Power Kit for Soundbars, hiding pesky cords behind the wall for a clean, sleek installation. The Extendable Soundbar Mount is available in black and white finishes and includes drywall, concrete and wood stud mounting hardware.
