Patent attributes
Metal panel siding systems incorporate panel clips and cover. The panel clips are mounted in linear arrays to a wall. The cover comprises a plurality of elongated metal panels having lateral side laps and a show side. The side laps extend inward from the show side. The panel clips comprise a first catch engaging a side lap of a first panel and a second catch engaging a side lap of a second, adjacent the panel. Thus, the side laps provide vertical seams between the adjacent panels. The first catch of the panel clips is mounted to the wall. The second catch is coupled to the first catch for movement from an unset position to a set position. The second catch does not engage the side lap of the second panel in its unset position, and engages the side lap of the second panel in its set position.
