NGP 220NDKB 48" DKB-finish Aluminum Automatic Door Bottom with Neoprene Seal offers a robust solution for enhancing the performance of commercial restroom doors. This door bottom is BHMA certified to ANSI/BHMA A156.22 and has successfully passed a 1,000,000 cycle test, ensuring durability and reliability in high-traffic areas. Crafted from Aluminum Alloy 6063 in T5 Temper, the NGP 220NDKB features a flame-resistant neoprene seal, providing excellent moisture resistance and temperature stability with a range from -81°F to 275°F. Its advanced elastomeric foam construction not only offers superior abrasion resistance but also withstands ozone, sunlight, and aging, making it ideal for various environments. Designed for easy installation, this model mounts on the push side of the door and works best with a threshold for maximum sealing capability. It comes with end caps and is available in a sleek dark bronze finish. The door bottom is handed, with a 7/8" maximum drop, and lengths ranging from 11" to 60" can be specified to suit your needs. For carpet applications without a threshold, a nylon brush is recommended. Elevate the performance of your restroom partitions with the NGP 220NDKB-where functionality meets quality.
