Almost all DSA Collections are available with a DP-50 Rating, with the exception of half-round units, exterior featured units (Dutch and Breezeport), and direct-set configurations. These high-performance units are tested in extreme conditions that simulate wind forces of up to 173 miles per hour. Our DP-50 units feature steel reinforced frames and double t-astragals for extra stability and security against hurricane-force winds.
