Protection plates (also called kick plates, mop plates, stretcher plates, and armor plates, depending on their height and placement) are applied to a door to prevent or minimize damage.
According to NFPA 80 “Standard for Fire Doors and Other Opening Protectives”, all hardware installed on a fire rated door must be labeled or listed, unless specifically noted otherwise in the standard. However, when it comes to protection plates, both labeled and non labeled plates are allowed. This can cause some confusion. When are the plates required to be a labeled product and when are they not required to be a labeled product?
The answer is provided in Section 6.4.5, which reads:
6.4.5 Protection Plates.
22.214.171.124 Factory-installed protection plates shall be installed in accordance with the listing of the door.
126.96.36.199 Field-installed protection plates shall be labeled and installed in accordance with their listing.
188.8.131.52 Labeling shall not be required where the top of the protection plate is not more than 16 in. (406 mm) above the bottom of the door.
If a protection plate is factory-installed to a fire rated door:
- The plate must be installed in accordance with the listing of the door.
If a protection plate is field-installed to a fire rated door:
- The plate is not required to be a labeled product as long as the top of the protection plate is not installed more than 16” above the bottom of the door.
- The plate is required to be labeled, and is to be installed per the plate manufacturer’s listing, whenever the plate is mounted more than 16” above the bottom of the door.
When reading the actual verbiage from NFPA 80, many people have interpreted the 16” requirement to mean that any plate less than 16” high does not require a label. However, this is not true. Consider a stretcher plate that is only 6” high. Stretcher plates are intended to be mounted on the door at a height where a stretcher or gurney would impact the door. This is usually in the range of 30” – 48” above the bottom of the door. So a 6” high stretcher plate, when used on a fire rated door, is required to be a labeled product because it is mounted “more than 16 in. above the bottom of the door”.
