About this item
- Automatic greenhouse ventilation – no electricity required. Opens and closes your greenhouse window using solar heat to maintain ideal growing conditions
- Strong 15kg lifting capacity – suitable for heavier greenhouse windows, providing reliable ventilation throughout the day
- Heavy-duty twin spring design – provides greater strength and stability than single spring models, helping lift heavier windows more reliably
- Adjustable temperature opening – starts to open between approx. 15–23°C and opens further as temperature rises
- Easy to install and use – suitable for aluminium and wooden frames. Before fitting, place the piston in the freezer for 10 minutes and push the pin inward until you feel firm resistance. Ensure the window can open freely to at least 45cm

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
