CHI 7000 Series Fire Doors

The CHI 7000 Series Guardian™ Fire Door is engineered to meet ever-increasing demands of property owners and insurance underwriters in a simple, easy-to-test, and reset fire protection product. Utilizing standard chain hoist operation, these rolling steel doors feature a reliable, safe procedure for frequent drop testing with a U.L. label rated from 3/4-hour to 4-hour protection. Manual push-up operation, fail-safe, and automatic reset motor operation models are optional to the Guardian standard.
