The 2" Field-Lok™ series is a mechanical field seamed panel system. The single-locked or double-locked structural panel can meet severe load requirements. For aesthetic reasons or personal preference, the panel can be seamed with a single fold displaying a broader seam. The single fold meets the needs for a structural panel while providing the reliability of a weathertight roof. The panel system is installed with an expansion clip.
