Review on 🔊 Pyle PSTND6 Speaker Bracket Wall Mount (Pair) - Adjustable Swivel Angle, Long Arm Distance, and Solid Steel Pin for Hanging Speakers on Flat Surfaces by Sean Tops

The product seems solid and for the most part I'd be happy, especially given the price. I have been buying Pyle products for many years. Problem: I have very small 12" Carvin PA speakers and these brackets can't even support their weight. They're supposed to hold 77 pounds, but my speakers are much smaller and won't work. I don't want them tipped down , but no matter how hard I tighten the hex bolts, they fall off. For the record, I'm a contractor and I know the tools and bolts, so that's not a problem. I tighten them all the way, I feel like the thread is ready to erase I didn't install them until the return window closed so now I'm stuck with a product that is useless.Will update review when issue is resolved.
