This product is BHMA Certified to ANSI/BHMA A156.22, ensuring it withstands up to 1,000,000 cycles, as well as extreme heat and cold conditions. Crafted from Aluminum Alloy 6063 in T6 Temper, it promises excellent strength and resilience. Designed to fit wood fire door mortise restrictions, this automatic door bottom features a neoprene seal that is moisture-resistant and flame-resistant, providing reliable sealing capabilities. It operates effectively within a temperature range of -81°F to 275°F, making it suitable for various environments.
