Automatic 600 mm electric chain window opener designed for reliable, hands ventilation and weather protection. Key benefits Convenience: Open and close windows remotely using the wall switch or the included remote control. Remote control works at any distance within 6 meters in a straight line. Weather protection: Builtin rain sensing function closes the window automatically when rain is detected, preventing water entry without manual intervention. Accessibility: Ideal for users with limited mobility; effortless operation removes the need to reach or manually operate heavy or hardtoaccess windows. Durable and low maintenance: Thickened aluminum alloy construction and double chain design resist rust and reduce maintenance needs. Quiet, efficient operation: Metal chain drive with low noise and low energy consumption. Overload protection stops the actuator automatically when push or pull force reaches a peak. Features Size: 600 mm stroke length. Material: Thickened aluminum alloy body and double chain mechanism, fine workmanship for long service life. Controls: Wall switch controller plus remote control. Remote effective range: any distance within 6 meters in a straight line. Safety: Overload protection stops movement when excessive force is detected. Performance: Low noise, low energy consumption, maintenance chain drive. Automatic closing: Rain sensing function closes the window automatically when rain is detected. Compatibility and installation Compatible with many window types: horizontal push, hung, middle hung, bottom hung, skylight, greenhouse window, double hung, sliding, roof, casement, and ventilation windows. Suitable for skylights, greenhouse vents, roof windows, and other hardtoreach or frequently adjusted openings. Can be installed where a 600 mm stroke is appropriate; check mounting clearance and window geometry before installation. Practical use scenarios Greenhouse ventilation: Automate vent opening and closing to maintain airflow while preventing rain from entering during sudden showers. Skylight or roof window control: Open skylights for daytime ventilation and close them automatically when rain is detected, without ladder access. Assisted living and accessibility: Allow elderly or mobilitylimited users to operate windows from the floor level using the wall switch or remote control. What makes it stand out A compact 600 mm actuator built from thickened aluminum alloy for durability. Double chain design for stable and reliable motion. Integrated rain sensing and overload protection for worry automated operation. Simple control options that improve daily convenience and safety. Technical reminder Confirm that a 600 mm stroke and the actuator mounting points match your window type and installation space before .
