CrossingGard Emergency Response Grilles

Model ERG10 for security and emergency egress access

Model ERG-IBC for security and Access Controlled Egress per the 2003 IBC®






CrossingGard is the only code compliant Emergency Response Grille designed to help address both security and safety issues in public areas. CrossingGard provides the security of a locked, rolling grille but immediately responds in an emergency situation to fully open automatically and allow safe escape. Available only from Cornell, the CrossingGard is always on duty to provide separation control, yet still allows access to an alternate means of escape.

Now, having received Evaluation Report ESR-1167 from ICC-ES (International Code Council -Evaluation Service, Inc.), CrossingGard® Model ERG-IBC is the only Emergency Response Grille successfully evaluated for access-controlled egress per the 2003 International Building Code®, Section 1008.1.3.4.


CrossingGard® Benefits:

  • Model ERG-IBC is ICC-ES evaluated as an access-controlled egress door per the 2003 International Building Code.

  • Fail-safe emergency response capability. When an alarm is sounded, power is lost or if an emergency exit push-button station is activated, the CrossingGard immediately clears the path by returning the grille to its full open position without requiring an electric or battery power source.

  • No manual locking or unlocking required. AutoLock automatically secures a closed grille by engaging upon attempt of forced opening. AutoLock remains disengaged during normal and emergency operation.

  • No resetting is necessary to resume normal operation. Following an emergency situation, the CrossingGard can be repositioned to the closed position by activating “close” at the motor control station.

  • Early Installation Option: Early/easy self-supporting installation system lets grilles to be mounted on factory supplied tubular members before walls are built and before there is a finished opening.


Openings from 5' to 24' wide and 4' to 20' high.


Cornell FS M100 series motor operator supplied as standard to provide daily operation along with fail-safe automatic emergency opening capabilities without the use of batteries or a back-up power source. Operator can be recessed above a ceiling, as no mechanical resetting is required to resume normal operation.

AutoLock Mechanism:

Concealed self-locking assemblies prevent forced opening of a closed grille. Lock mechanism will not interfere with normal electric, fail-safe or emergency response self-opening feature.
