Arrived safely. Packaging could have been a bit more protective (box was crushed). Product seems to fit the bill. Yet to fit.

My Greenhouse is 25 years old and the roof vent packed in this year. Never thought I would be able to get a new one, However your catalogue proved me wrong I found the information good ,only one comment it would help me in the future to have the overall length included.Is 5 the highest rating

Very quick and efficient delivery. Haven't attached the auto opener yet, as I need another pair of hands!

by Helen Weedon

A must have for a greenhouse! I purchased one after I had erected my new greenhouse and it does the job. It has variable adjustment control for the temperature so you can choose how warm you need the greenhouse to be before it opens. It is easy to install. Highly recommended!
