This quality greenhouse vent opener automatically opens and closes your greenhouse window as the temperature changes. This model is fitted with a heavy duty double spring mechanism designed for use in exposed locations or on lightweight polycarbonate glazed vents which do not have sufficient weight to prevent the wind opening the vent unintentionally. With a unique action and smooth twist free operation this unit incorporating double upper arms has a strong bracket assembly and includes extra strong springs to provide a very positive closing action. It is recommended for use on both aluminium and timber roof and top hung side vents, particuarly light polycarbonate glazed, in exposed areas to reduce wind snatch effect and provide increased resistance to wind flutter. Finished in a durable polyester powder coating and corrosion resistant throughout. It will lift up to 6 kg (13.25lbs), i.e a vent weighing up to 12 kg (glass area not exceeding 0.65m² in an aluminium frame), with a maximum opening of 35cm (14 inches). PLEASE NOTE: If you have one of the newer type of polycarbonate greenhouses which "trap" the plycarbonate in the frame these will not simply clip on as per the instructions, you will simply need to drill 4mm holes in the vent to bolt through.

does exactly what it should, recommend if you need good control
Needed a self closing strong control for my new greenhouse, walls are polyacrilic,so have no weight to close simple mechanism. Easy to adjust by holding open slightly, has coped well with 60mph winds trying to open window.

Good Heavy duty design
Very strong window opener; I use these for a log cabin with wooden double glazed windows. They have no problem lifting the window open; and they close very tight on the seals at night to keep out the cold. Good Heavy duty design.
