NGP 520NDKB 48" DKB-finish Aluminum Heavy Duty Surface, Automatic Door Bottom with Neoprene Seal is engineered for superior performance in commercial restroom environments. Constructed from durable Aluminum Alloy 6063 with a T5 temper, this automatic door bottom promises longevity and reliability. It is BHMA certified to ANSI/BHMA A156.22, ensuring it withstands 1,000,000 cycle tests, making it ideal for high-traffic areas. This product features a synthetic EPDM rubber seal encased in a polypropylene thermoplastic matrix, offering excellent moisture resistance and a temperature range from -81°F to 275°F. Additionally, it boasts high abrasion resistance, flame resistance, and is designed to perform well against ozone, sunlight, and aging. The NGP 520NDKB mounts on the push side of the door, and for optimal sealing, it is recommended to use it with a threshold. In carpet applications without a threshold, a nylon brush is advised. The unit is available in a sleek black color with a dark bronze finish, providing a modern aesthetic that complements any restroom design. For precise fitting, specify the exact net length required, as lengths are available from 11" to 60", with specific cutting recommendations based on size.
