NGP 222NDKB 48" DKB-finish Aluminum Automatic Door Bottom with Neoprene Seal delivers exceptional performance and durability for commercial restroom applications. This automatic door bottom is BHMA Certified to ANSI/BHMA A156.22, ensuring it meets rigorous performance standards, including a 1,000,000 cycle test for Grade 1 durability. Constructed from Aluminum Alloy 6063 with a T5 temper, this door bottom offers excellent resistance to moisture, ozone, sunlight, and aging, making it ideal for various environments. The neoprene seal, made from synthetic EPDM rubber in a closed-cell matrix, provides superior abrasion resistance and memory, ensuring a reliable barrier against drafts and moisture. With a maximum drop of 7/8", the NGP 222NDKB is designed to mount on the push side of the door, optimizing sealing capabilities when used with a threshold. For carpet applications without a threshold, a nylon brush is recommended. The product is available in a sleek dark bronze finish and can be ordered in lengths ranging from 11" to 60", with specific length requirements to avoid field sizing. This automatic door bottom not only enhances functionality but also contributes to energy efficiency and comfort within your restroom spaces. Its flame-resistant properties further enhance safety, making it a smart choice for any commercial setting.
