Watch the 324 Grille in action

Extreme 324 Performance Grilles operate 3X faster than standard coiling grilles and perform to an exceptional 300,000 cycles.

Opening quickly at 24" per second and closing at 12" per second, our 324 Grille was designed to meet the challenges of high-traffic openings in applications like parking facilities and government buildings.

Backed by an industry-leading 5 year warranty, the 324 Performance Grille's continuous duty operator, advanced control system, self-lubricating guide design and self-supporting installation option will maximize your facility's productivity, promote smooth traffic flow and reduce downtime.

The open air design provides visibility and ventilation, and you can complement your building aesthetics with straight or brick pattern curtain designs.
