If you are installing a pad-mount pedestal pole on existing concrete, then this kit is what you need to do it. These 7" by 5/8" anchor bolts are used to install studs into an existing cement pad/foundation. They are installed by drilling holes into the concrete, then tapping the studs into the holes. As the nut is tightened, the stud will move upwards slightly allowing the anchor to "grab" the wall of the hole. The expanding washer will fill the space and permanently anchor the stud into the concrete. Great to use with any pad mount pedestal. Below is a diagram of the recommended installation.
