R&S Erection of Santa Clara County, Inc.

A service Company

Fire Rated Service Doors

R&S Fire Doors combine the durability, security, efficiency and space saving advantages of a rolling service door with the

added life and property saving benefits of automatic fire protection. Underwriters Laboratories, Warnock Hersey and Factory

Mutual up to 3-Hour/Class 'A' Label or Oversize Certificate of Compliance is furnished standard.

Refer to the Listing Summary below for conditions affecting approvals by various testing agencies. Acceptance of the listing

for variations in wall construction should be verified with the building authority having jurisdiction.

[Fire Door Release Mechanism Detail]

Fire Doors are designed to close automatically from a fully open position - activation of the door in the down position may cause damage. Fire Doors are not designed for use in high cycle applications - a secondary non rated door is recommended in those situations.
