Frequently Asked Questions
Q: Do these require batteries?
A: No, these are purely mechanical and use a wax-filled cylinder that expands with heat to move the piston.
Q: Can I manually close the window?
A: Yes, but keep in mind that the unit relies on temperature to operate, so forcing it might damage the piston seal.
Q: Will this fit my greenhouse?
A: Most universal vent openers fit standard aluminum-framed greenhouses, but always check your mounting points before purchasing.
