The Von Duprin 210NL689 night latch trim provides outside access control for 22 Series exit devices with its durable 689 aluminum finish. This trim component allows authorized personnel to enter through exit-only doors while maintaining the building's security perimeter. The lacquer-sprayed aluminum construction resists corrosion and daily wear in high-traffic commercial applications.
This night latch trim meets ANSI/BHMA A156.3 standards for exit device hardware, ensuring reliable performance in emergency egress systems. The 689 finish matches standard aluminum door hardware and frames for consistent appearance across building entrances. Installation requires standard tools and follows Von Duprin's established mounting procedures for 22 Series devices.
Common applications include office buildings, schools, healthcare facilities, and retail spaces where controlled access through fire exits is required. The night latch mechanism allows key holders to enter while preserving the exit device's free egress function from the inside, making it ideal for employee entrances and service doors that must remain compliant with fire codes.
