NGP 225S-60 Mill Aluminum Mortise Automatic Door Bottom with Silicone Seal is engineered for durability and exceptional performance in demanding commercial environments. Certified by BHMA to ANSI/BHMA A156.22, this automatic door bottom is rigorously tested for quality and reliability, ensuring it withstands up to 1,000,000 cycles. Constructed from aluminum alloy 6063 with a T5 temper, the NGP 225S-60 offers superior strength and resistance to wear. Its silicone seal is designed to be flame-resistant, moisture-resistant, and remains flexible across a wide temperature range of -100°F to 500°F. This versatility makes it suitable for various applications, including areas utilizing FM200 or Halon fire suppression systems. The door bottom is available in lengths from 11" to 60" and features a maximum drop of 7/8". It is furnished to be 1/2" shorter than the ordered length to fit net door sizes seamlessly. For optimal sealing, it is recommended to use with a threshold, and a nylon brush can be added for carpet applications without a threshold. With excellent resistance to ozone, UV, and aging, the NGP 225S-60 is built to last, making it an ideal choice for building professionals seeking reliable and effective restroom partition hardware.
