NGP 423N36 36" Neoprene Heavy Duty Mortise Automatic Door Bottom, Mill Aluminum FinishNational Guard NGP 423N36 36" (3') Neoprene Heavy Duty Mortise Automatic Door Bottom in Mill Aluminum Finish is designed to provide exceptional weatherization and durability for commercial applications. Crafted from a synthetic rubber polymer blend that includes PVC, Nitrile rubber (NBR), and Chloroprene closed cell advanced elastomeric foam, this automatic door bottom ensures superior abrasion resistance and tensile strength. This product operates effectively across a wide temperature range of -20°F to 200°F, making it suitable for various environmental conditions. The neoprene insert not only offers excellent moisture resistance but is also flame resistant, ensuring safety and reliability. The 36" insert size and 3/4" thickness provide a snug fit, effectively sealing gaps to prevent drafts, dust, and moisture from entering your space. The flange is made of durable aluminum with a mill finish, featuring a length of 36", a width of 1-1/2", and a thickness of 7/8". This ensures both structural integrity and aesthetic appeal. Additionally, the National Guard NGP 423N36 comes with a limited 5-year warranty, reflecting the manufacturer's commitment to quality.
