Step-by-step guide
- 1Look for labels on the door and frame, usually near the hinges; some labels are on the top or another edge because of hardware.
- 2Record the listed duration, manufacturer, and any special limitations shown.
- 3Confirm that the door, frame, glazing, and hardware are compatible as one listed assembly.
- 4Follow the project documents and local authority requirements; do not infer a rating from appearance.
Guide notes
A fire-rated opening is a complete listed assembly, not only a rated door leaf. Read both door and frame labels, use compatible glazing and hardware, and follow the project documents and local authority having jurisdiction. Never assume a rating because components look similar.
