The independent Architectural Testing laboratory subjected our ShutterUp Latches to a week’s worth of intense simulation of storm conditions, including Category 3 hurricanes. We passed with flying colors. ShutterUp Latches are tested to Florida Building Code standards ASTM E 330 and ASTM E 1886/1996. The videos were shot using our little camera so they are a bit rough, but they show just how ShutterUp Latches performed under extreme conditions.
