Sound Bass Sonos Beam Wall Mount Bracket, Black, Includes Mounting Hardware Kit to Hang Your Soundbar, Designed in The UK by Soundbass

Q: Does it come with the screws to hold the Sonos Beam?

Yes. It comes with everything needed to seamlessly mount the Beam.

Q: Add on question to the Bose mount question... Can these brackets be mounted to wall and any soundbar with 4" depth just sit on them?

yes for for mounting but will vary on sound bar

Q: Can i use this for other sound bars? ie. Bose 500

This is designed ONLY for the SONOS BEAM, we do have Bose 500 wall mounts, but at this time they are out of stock

Q: What size drill bit to use for the drywall mounts?

In general with these types of drywall mounts, the plastic piece should have a slight friction fit. Basically you should be able to push it 90% of the way in with your thumb but it shouldn’t be able to slide in and out easily. So hold up a bit next to the plastic piece and find the bit that is slightly smaller diameter than the plastic part. Error on being too small because you can always make the hole bigger by using the next size up drill bit. It is much harder to make the hole smaller.
