Described is a removable assembly for use on a fixed surface. The assembly includes a post having a base (42) and an attachment assembly (8). The attachment assembly includes a base plate (10) and a magnet assembly (12), both capable of carrying a magnetic current. The magnet assembly includes a housing (20) and a magnet (22) disposed within the housing. To use, the magnet assembly is placed adjacent the base plate, the magnetic forces attracting and holding them together. The magnet is positioned apart from the base plate while the housing contacts the base plate to form the magnet circuit. An attachment plate (30) is connected to the housing upper wall adjacent its outer surface. The attachment plate includes one or more outwardly projecting attachment bolts (26). As assembled, the bolts engage corresponding openings (48) in the post base (42).
