Spiral® LH® High-Performance Door
The Spiral LH (Low Headroom) door delivers true high-speed performance where space is tight and traffic is constant. Engineered to meet low headroom requirements for parking garages and commercial structures, it combines rapid, reliable operation with rigid aluminum slat strength—eliminating the need for a second security door while maintaining a clean, modern look. Perfect for government, parking, security, and automotive dealership applications, the Spiral LH is also available with full-vision or full-ventilation slats (up to 18′ wide) to match the visibility or airflow needs of your environment. And with a 5-year limited warranty on motor/mechanical components and materials plus a 2-year limited warranty on electrical components, it’s a smart, long-term upgrade for demanding sites.
