Oasis G/H Automatic Opener (9360576) from TwoWests & Elliott

Designed specifically to fit the roof vents of the Oasis Modular Greenhouses and Lean-Tos, this Automatic Opener will open and close according to the temperature.

 Replaces the window stay on the greenhouse roof vent.

Works by the mineral wax within the cylinder expanding with heat, which then pushes a piston to open the vent. As the temperature falls the wax contracts and the vent closes.

Fits neatly close the frame the opener does not protrude into the greenhouse - so you don't bang your head!

Please note: designed for use with the Oasis Modular Greenhouses and Lean-Tos ONLY.
