- fire door
- fire exit hardware
- door closers

- Class “B” (1 hour)-Openings in enclosures of vertical shafts and stairwells through buildings and in 2 hour rated partitions providing horizontal fire separations
- Class “C” (3/4 hour) – Openings in walls or partitions between rooms and corridors having a fire resistance rating of 1 hour or less.
- Class “D” (1 1/2 hour) – Openings in exterior walls subject to severe fire exposure from outside the building.
- Class “E” (3/4 hour) – Openings in exterior walls subject to moderate or light fire exposure from the outside of the building.
- No letter designation (1/2 or 1/3 hour) – Openings in walls or partitions between rooms and corridors having a fire resistance rating of 1 hour or less. Note that these doors are not really considered fire doors, but rather used for smoke control only.
