If you are looking for a easy post-to -concrete connection, this is it. The galvanized steel base is wrapped around the post with a nice curve profile at the top. The bases secure to the post with six structural screws, and to the concrete with epoxy and a concrete screw or a wedge type anchor. A lexan spacer between the post and concrete provides a long term gap between these two surfaces.
If you need more uplift you can add them to all four sides. As always, consult an engineer in your area about your structural needs in your site location, they all vary.
