Review on Flange Square Included Anchor Bolts by David Urbanski

The listing picture says you should use a 1/2" drill bit to drill holes for the anchor sleeves, but 1/2" is too loose and you need to pre-install that Grip anchor perforated walls. A 7/16" bit would probably fit better, but I didn't have one. I didn't have time to return it to finish the job, so I had to work 3x harder to get it installed the way I was supposed to. Despite all that After the extra work I'm not happy with the durability as they are a little loose on the stand.Self tapping screws bring some stability but are still too wobbly.Now I'll have to drill out the anchor sleeves and replace them with larger anchors and I'll probably do the posts fill with quick-setting concrete to stabilize them It's a good idea, but there are a few design flaws that make them more problematic than they're worth.
