Automatically opens and closes your greenhouse window as the temperature changes. Complete kit, ready to install with easy to follow instructions. Fits most greenhouses. Unfortunately if you have one of the "trapped polycarbonate" type of greenhouse which are currently being sold on the internet there is nothing for the clamps to fit onto and these units will not be suitable for you. This opener is the latest in a line of THERMOFOR roof vent openers designed and supplied over the past 50 years. This model is an attractive cost effective unit with a unique opening action, ensuring a smooth twist free operation, and with the cylinder mounted within the bracket to eliminate projection in the greenhouse. It is finished in a durable polyester powder coating and is corrosion resistant throughout. Easily fitted to Aluminium and wooden greenhouses it will lift up to 7kg (15.45 lbs), i.e a vent weighing up to 14kg (glass area not exceeding 0.75m² in an aluminium frame), with a maximum opening of 35cm (14 inches). Manufactured in the UK by a company with 50 years experience of these vents - please do not compare with cheap far east copies.

Small & compact, they do exactly what they're intended to do
These are just great! They do exactly what they're supposed to do. Easy to install & adjust. I originally wondered whether they would work on the vertical wooden sashes that open outward from the bottom on my salvaged sash & barnwood greenhouse. An email to the manufacturer received an immediate reply along with a PDF of the instruction sheet. Small & compact; they do not have a cylinder that projects into the room which would have been in the way on my installation. I needed 5 but only purchased 3 untill I knew how well they worked. They work so well that now I need 2 more!Shipping was from Europe & I received them 5 days after the date of order! That's better than some "2 day" shipping! Pay the extra 2 dollar upshipping charge, it's worth it.One important note: remove during the winter if your greenhouse is seasonal. It got down to -33 degrees last winter & I was told to remove the cylinder over winter.But then again, I'm just a FOG & what do I know.

well made, works well.
I put this on a 6 ft x 8 ft Harbor Freight greenhouse and it works well. Some time ago I had tried a similar unit from Harbor Freight but had to return it unused because it had leaked oil while new in the box. After reading all the 1 star reviews on other openers I chose this one and from appearances it seems to be better made than the HF one.
