NGP 683A-60 Heavy-Duty Anodized Aluminum Mortise Door Bottom with Nylon Brush Seal

NGP 683A-60 Anodized Aluminum Heavy-Duty Mortise Automatic Door Bottom with Nylon Brush Seal provides a robust solution for enhancing door performance in commercial settings. Crafted from durable Aluminum Alloy 6063 with T6 temper, this door bottom is designed to withstand rigorous use while maintaining its integrity. The nylon brush seal offers excellent abrasion resistance, flexibility, and memory, making it an ideal choice for applications where a threshold is not installed. Engineered for moisture resistance, the NGP 683A-60 features an EPDM rubber insert that effectively guards against water penetration, ensuring a tight seal for exterior doors. Suitable for wood fire doors, it meets specific mortise requirements with a drop of up to 3/4". This product is available in lengths ranging from a minimum of 11-1/2" to a maximum of 60", and it is furnished 1/2" shorter than ordered to ensure a perfect fit. With black plastic end caps included, this automatic door bottom not only enhances functionality but also maintains a clean appearance. For optimal performance, specify the exact net length required to avoid field sizing. The NGP 683A-60 is ANSI/BHMA certified, ensuring compliance with industry standards for door gasketing and edge sealing systems.
