Rolling Security Grilles (Up-Coiling)

Combining robust physical security with maximum visual clarity and airflow, Overhead Door Up-Coiling Security Grilles provide reliable access control for high-traffic commercial environments. At Timbers-Kovar, we supply and install these overhead coiling grilles to protect retail storefronts, parking garages, school hallways, and healthcare facilities.

Engineered to coil neatly above the door header when open, up-coiling grilles keep sightlines completely unobstructed during operating hours while establishing a formidable defense when closed.
