Review on 🔊 Stainless Steel Ceiling Speaker Mounts, Horizontal 360° Full Adjustment, Holds up to 90lbs, Ceiling Mounting Brackets for Large Surround Sound Speakers (2-Pack, Black) by Kevin Woods

If they had quality control I wouldn't have had to drill holes for the screws they sent. Once you figure out how to assemble them (no instructions) they are very stable! No damn mounting hardware either! For your speakers or for mounting. What? But I like what they are. Toggle switch with two separate bolts to hold this position! Also, I've hung some fairly old and heavy speakers on it and the whole mount holds up perfectly! So a total of 3! Did what I needed just not all inclusive as our culture took root too!🤙🙃
