Safe, simple, inexpensive and repeatable drop testing is made possible in any facility with a flip of a handle. C.H.I.'s Guardian™ Fire Doors promote achievable standards for drop test compliance by making the job safe, understandable and simple for everyone. Simple test fire doors are our standard for chain hoist and motor operated doors. Choose from models in a variety of gauges and U.L. label ratings from 3/4-hour to 4-hour protection.

Manual push-up, chain hoist and automatic reset motor operation is available for Guardian™ Fire Doors and can incorporate one of several release device options. The National Fire Protection Association (NFPA) and other model codes recommend frequent drop testing of rolling steel doors to ensure a continuous state of operational readiness. C.H.I. strongly promotes these recommendations with the Guardian's™ advanced design features.

Rolling Fire Doors are available in a variety of gauges, materials and fire-ratings to achieve your project requirements.
