ProSteel Door Fire Protection Features
NFPA 252 Compliant
ProSteel doors have a 3-hour fire rating and meet the standards of the National Fire Protection Association (NFPA) 252 code and guidelines.
Palusol Fire Seal
The ProSteel Vault Door has a Palusol fire seal around the entire inside perimeter of the door that expands to nearly 7 times its original size when heated. This seal increases the fire resistance and protects your valuables from water damage that might occur in fire-fighting efforts.
