LCN 4040SEH-3038 120V 689 Standard Track AL is a robust, heavy-duty closer/holder designed for fire and smoke barrier doors. This non-handed, non-sized device provides a reliable single point hold-open function, ensuring doors remain open until current interruption releases the mechanism, allowing for safe closure. Ideal for interior doors up to 4'0", the 4040SE series is engineered with a single lever track arm that enhances usability and efficiency. The hold-open force is adjustable, providing flexibility based on specific needs. A momentary on/off switch board assembly allows for easy testing of the door release while offering over-voltage protection, making it a practical choice for various environments. It functions seamlessly as a full rack and pinion closer when the hold-open feature is not engaged or if current is interrupted. Designed for commercial installation, this closer mounts on either the push or pull side of the door, ensuring versatility in any setting. It is compatible with alarm systems and offers concealed or surface wiring options. Finished in a matte silver (689/US28), it meets ANSI A156.15 standards and is ADA compliant. Backed by a two-year limited warranty, the LCN 4040SEH-3038 delivers both safety and functionality for demanding environments.
