This 14 11/16" diameter aluminum base can be mounted permanently to a concrete or a paved surface or it can be used for temporary signs. It can be used with u-channel posts, square posts, or pipe posts. It works with a 2 lb-per-foot u-channel post. It will not work with a 1.12 lb-per-foot u-channel post. If you are using round posts, holes will need to be drilled in the round posts and they will need to be attached with bolts (not provided). To install this aluminum bass, you will need three concrete anchor bolts and a drill with a masonry bit. A variety of 5/8" concrete anchors bolts should be available at your local hardware store. If you install it on asphalt, 12" asphalt "spikes" are recommended and available at some hardware stores and from various online stores.
