Review on Enhance Your Audio Setup with Jumbl SINSB7B ProGrip Ultra Stainless Steel Speaker Wall Mount Brackets (Set of 2) by Wayne Ohlrogge

I knew from previous reviews that I would need anchors or screws to install this, but what I didn't know was that the screws for the EZ anchors I already had had too narrow a head to hold this bracket. I ended up having to use other less desirable anchors I had. The next problem is that since they are designed for Definitive Technology speakers whose mounting holes are on the bottom of the speaker but can work with any speaker, a 5mm Allen key is included. too short to reach with the long side of the Allen key needed to fasten with enough force to hold the speaker. I have SVS Prime Satellite speakers (6.5 pounds each) which have a mounting hole in the middle of the back of the speaker. I turned the speakers sideways as another reviewer suggested, but they were still difficult to reach. I ordered a 5mm allen key for Martin acoustic guitars. This wrench is long on both sides of the right angle so it's long enough to reach the wall mount behind the speaker and long enough on the other side to give me enough leverage to tighten the fastener. all metal well done but it would be much better if they just provide you with anchors then you have the right size broad head screws and you could use the provided screws with anchors in drywall or directly in the stand. And if you're using it on speakers other than those with Definitve technology, it's recommended that you buy a 5mm longer Allen key. This is the one I got (https://smile.amazon.com/gp/product/B07R4HJH5F/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) which made assembly 20x easier.
