These amazing devices are made in our own workshop in Staffordshire
• Opens your greenhouse roof vent automatically as the greenhouse heats up
• Provides ventilation to plants when they need it most
• No electricity required - powered by heat expansion alone!
• Easy to fit - adaptable to any aluminium or wooden greenhouse On most aluminium greenhouses, it simply clamps on.
Fitting an auto opener can help you regulate the temperature in your greenhouse and maximises the potential of the roof vents. Controlled by heat alone they do not take batteries or need an electricity supply.
The unit can be adjusted to change the operating temperature to suit.
Guaranteed for two years.
