High Security and High Speed, Designed for Applications with Low Headroom

The Spiral® LH® (Low Headroom) door offers high-speed for high-traffic situations while meeting the low headroom requirements of parking garages or other commercial structures. Rigid, aluminum slat construction eliminates the need for a second security door and crisp lines give the Spiral LH a stylish look. The Spiral LH door is ideal for automotive dealerships, government, parking and security. Also available are models designed with 9-inch tall full-vision or full-ventilation slats for specific applications or environments. 

The Rytec Spiral® door portfolio includes models certified to withstand winds up to 175 miles per hour.
