LCN 4310ME-3077SF LH 689 Swing Free Arm AL

LCN 4310ME-3077SF LH 689 Swing Free Arm AL is a concealed heavy-duty, electrically controlled closer designed specifically for fire and smoke barrier doors. This left-handed model allows infinitely adjustable hold-open functionality, ensuring doors remain securely open until a current interruption releases the mechanism, allowing the door to close automatically. The single lever (track) arm design is tailored for interior applications, making it ideal for commercial environments. It features a standard 2310ME series closer, which can be shipped with either a 24V or 120V cylinder. The closer accommodates interior doors up to 4'0" in size and operates as a full rack and pinion door closer when the hold-open feature is disengaged or interrupted. Built with a practical "On/Off" switch, the hold-open function is easily controlled. This model interfaces seamlessly with fire alarm systems, ensuring compliance with safety standards. A matte silver finish (689/US28) provides a sleek look, and options for a custom powder-coated finish and plated hardware are available. Designed for commercial installation, the LCN 4310ME-3077SF delivers reliability and safety in high-traffic areas, making it an essential component of any building's access control system.
