The Spiral Low Headroom (LH) 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 is ideal for automotive dealerships, government, parking and security. Benefits Special track design allows a door to fit with as little as 11 inches of clearance. Innovative engineering uses a compact, variable speed motor to achieve opening speeds up to 60 inches per second within a smaller footprint. Counterbalance system, patented spiral design and AC drive reduce wear and increase door longevity, with minimal preventative maintenance.
