Abstract: A system for the preparation and installation of building exterior panels is presented which is both economical and practical. In the described embodiments, edge mounting members having anchor teeth are assembled on all four sides of a laminated aluminum panel having routed out edges. Anchor sockets having anchor teeth indents adapted to mate lockingly with the anchor teeth of the edge mounting members are affixed to the building frame in a mating relation to the edge mounting members and in a location to accept the panel. The panel is snapped into engagement with the anchor sockets locking the anchor teeth into the anchor teeth indents obtaining a permanent attachment. Individual panels may be replaced in case of damage.
