I used a hammer and wrench with the bolts they came with to secure them to the concrete. They seem like they will last a long time. I ended up having to order a 2nd one because I only bought one at first. I don’t know what I was thinking but still a little annoyed that one wasn’t enough and I had to purchase another, which I hadn’t planned on. ⅗ because they should sell them as a 2 pack or discount the 2nd one.
