 GuardianTM Fire Doors
The GuardianTM Fire Door system by C.H.I. is engineered to help save property, and more importantly, save lives. Manual push-up, chain hoist and automatic reset motor operation is available for GuardianTM Fire Doors and can incorporate one of several release device options.

C.H.I. strongly promotes these recommendations with the Guardian’sTM advanced design features.
