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

Spiral® LH® High-Performance Door

The Spiral® LH® (Low Headroom) door offers high-speed for high-traffic situations. It meets low headroom garage door 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. 

The Rytec Spiral® door portfolio includes models certified to withstand winds up to 175 miles per hour. See our hurricane-rated doors.
