Enhanced security is provided by re-engineered automatic latching panels and improved weather protection from redesigned perimeter seals and tight-fit clamps. It also boasts an integrated water drainage system, a 400 lbs. weight capacity (evenly distributed), and a 5-year warranty, and is assembled in Missouri.
