Emergency Response Security Grilles
CrossingGard® is an Emergency Response Grille designed to help address both security and safety issues in public areas. CrossingGard® provides the security of a locked, rolling security grille — but immediately responds in an emergency situation to fully open automatically and allow safe escape. Our exclusive egress safety grille is always on duty to provide separation control, yet still allows access to an alternate means of escape.
A secure emergency solution that combines secured roll down gate space separation with emergency egress capability. If notified by alarm, if power fails or if the emergency exit push-button is activated, the rolling security grilles immediately execute a fully open position with no electrical requirements whatsoever. Post-event, it can resume the normally overhead security grille closed and secure position with the touch of a button.
The rugged, open pattern interior gates provide security and visibility with little-to-no maintenance. Manual locking or unlocking is not required. When a forced security grille opening is attempted, AutoLock automatically secures any closed rolling grille (while remaining disengaged during normal and emergency operation).
The CrossingGard® provides excellent security grille corridor protection for flexible space requirements, separation control in facilities where emergency personnel need quick access to secure areas, and containment options for openings requiring a means of egress, such as schools and government facilities.

Trim PackageIn applications where exterior aesthetics are important, such as hotels, condominiums, convention centers and parking garages, the addition of a trim package can cover unsightly hardware and contribute to the building's architecture.
Seismic Performance Validation
We can provide project specific seismic calculations for all coiling doors that are mounted Face of Wall to steel or masonry. Seismic performance validation is per ASCE 7-05.
Entrapment Protection Devices
Entrapment protection devices ensure that a motorized door or grille will not close on an object. If an object enters path of closure, the entrapment protection device will stop the door or grille from closing and return it to the fully open position.
