About This

  • 【Solar Automatic Window Opener】The automatic window opener can adjust the size of the window according to the room temperature. The temperature is automatically adjusted to 15 to 25 degrees Celsius, and as the temperature rises, the black tube expands and expands, raising the window. The temperature drops, the window opener is lowered, and the window closes
  • 【DOUBLE SPRING DESIGN】We upgraded the old single spring to double spring, and the maximum bearing force has been increased from 7kgs/15lbs to 15kgs/33lbs, so that the window opener can not only be used in lightweight aluminum alloy windows, but also used on wooden windows.Working ConditionThe maximum height of the open window is about 45 cm (18 inches)
  • 【High Quality Material】Crafted from premium-grade anodized galvanized steel, this window opener guarantees long-lasting performance. Greenhouse vent opener can withstand the demands of greenhouse environments, ensuring it remains your trusted gardening companion for years.
  • 【No Batteries Required】Our automatic window opener is completely self-sufficient and doesn't rely on batteries or electricity for operation. No additional power source is needed, saving you money and reducing environmental impact
  • 【Easy to Install】Comes with an accessory package and a detailed manual for easy installation. Note: For the first use, it is recommended to place the gas rod between hot water at 35-45°C for 30 minutes, if the gas rod is extended, the gas rod is normal. If the pneumatic rod is stuck and does not work, apply lubricating oil to the threaded adjustment tube and piston rod and manually stretch the piston rod several times.

    Loved the wildflower seed mix—sprouted fast, and the pollinators showed up within a week. Great way to help the bees!

    The cedar raised beds I ordered from GARDUCT smell amazing and feel rock‑solid. Absolutely worth every penny compared to the flimsy ones at big‑box stores.
