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.
