NGP 520NDKB 36" DKB-finish Aluminum Heavy Duty Surface, Automatic Door Bottom with Neoprene Seal offers exceptional performance and durability for commercial restroom partitions. Constructed from Aluminum Alloy 6063 with T5 temper, this automatic door bottom is designed to withstand rigorous use and is BHMA certified to ANSI/BHMA A156.22 standards, ensuring reliability through a 1,000,000 cycle test-Grade 1. This model features a neoprene seal made from synthetic EPDM rubber in a polypropylene thermoplastic matrix, providing excellent moisture resistance and a temperature range from -81°F to 275°F. Its flame-resistant properties and robust design contribute to superior abrasion resistance and tensile strength. For optimal sealing, it is recommended to use this product with a threshold; for carpet applications without a threshold, a nylon brush is suggested. The NGP 520NDKB is available in a sleek dark bronze finish and comes standard with end caps. It can be cut in the field for lengths of 36" and longer, while lengths under 36" should be ordered to exact specifications. With a maximum drop of 7/8", this automatic door bottom ensures a tight seal that effectively controls drafts and smoke, making it a smart choice for both functionality and safety in commercial settings.
