Monzlteck Wall Mount for SONOS Move

Will you be offering a white option soon? Our Moves are white and was hoping to match the bracket to the wall and speaker.

can this be mounted outside? New York weather

What is the width of the shelf? Not the package.

Is the wall plate mounted to the wall independently to what the illustration shows for the vertical stabilization bar? i.e. are there 2 or 4 screws?
