The FireStar fire-rated counter shutters from Wayne-Dalton have an automatic closure in case of fire but is operable for daily use. The shutter’s single-side cable system, used in conjunction with the lockable test station, allows it to be tested and rest in minutes, and its drop-out mechanism is designed to eliminate downtime. FireStar comes in sizes up to 16' high and 8' wide. Model 540 is made of prepainted galvanized steel; model 550 is made of brush-finished stainless steel. Both use a 2" flat slat.
