Review on Plastic Expansion Drilling Concrete Curtains by Devin Jirsa

Had to hang a 2-hole bracket from the ceiling. 8" I couldn't fully insert the dowel into the hole. When drilling 3/8" both anchors fit well. The bracket holds a pendant light with a tension chain so I had to be careful when pulling it not to come out of the ceiling. I used the screws that came with the anchors Now I'm pretty sure it must be a lot of weight to get that out of the ceiling.
