LCN 4040SE-3077T 632 Standard Track Arm US3 offers a robust solution for fire and smoke barrier doors with its heavy-duty, non-handed design. This door closer/holder is engineered to provide a reliable single point hold-open feature until current interruption activates the release mechanism, allowing the door to close securely. Crafted with a bright brass finish, the 4040SE is not only functional but also aesthetically appealing for commercial environments. Designed for interior doors up to 4 feet wide, this closer includes a standard arm and an SE track, available in either 24V or 120V configurations. The hold-open force is easily adjustable, giving you control over its operation. When the hold-open feature is disengaged, it functions as a full rack and pinion closer, ensuring efficient door management. Installation is versatile, as the closer can be mounted on either the push or pull side of the door, with concealed or surface wiring options for seamless integration. Its compatibility with alarm systems enhances safety, while the UL 10C listing ensures compliance with fire safety standards. Backed by a 2-year limited warranty, the LCN 4040SE is the ideal choice for professionals seeking durability and reliability in door hardware.
