Why the Spiral^® LH^®

The Spiral^® LH^® (Low Headroom) door offers high speeds for high-traffic situations. It meets low-headroom requirements for parking garages and 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 government, parking, security, and automotive dealerships. Also available are models (up to 18′ wide) designed with 9-inch tall full-vision (-FV) or full-ventilation (-VT) slats for specific applications or environments.

The Spiral LH is backed by a 5-year limited warranty on motor/mechanical components and materials, plus a 2-year limited warranty on electrical components.
