High-Performance, Low Maintenance
These security grilles are built for long-lasting, trouble-free performance. The counterbalance assembly features heavy-duty helical torsion springs in a steel tube or pipe barrel to provide long and reliable service. Guides feature continuous wear strips for ease of operation and noise reduction. Surfaces are factory pre-finished to minimize field preparation and enhance the finish’s durability. Optional crank or electric motor further simplifies grille operation. An optional heavy usage package provides extended life in applications requiring higher-duty cycles, such as parking garages and service access gates.
