Plenum-Rated Aluminum Pipe and Duct Markers withstand extreme temperatures, moisture, abrasion and chemicals without yellowing, fading, peeling or becoming brittle. Markers meet or exceed ASTM E-84-03 Standard Method of Building Materials. Aluminum material is designed to self-extinguish with low flame-spread and smoke-development ratings. Ideal for use in boiler rooms, attics and anywhere extreme heat and conditions are present in industrial facilities. Strong adhesive backing keeps marker securely affixed to ductwork. Bold colors, text and arrows facilitate quick and accurate identification for maintenance, troubleshooting and emergency response.
