I had looked around to wall brackets for Sonos Play 3 boxes (4 x in our household), and have only the expensive systems (approximately 40-50 per box) found. If you are looking for ordinary boxes Wall mounts, then you get to this system. Simple and solid to attach to the wall and super easy to attach by means of a M6 threaded rod to the Sonos boxes and for about 7-8 per box. Definitely a strong buy recommendation.
