Woodside XL Solar Heat Sensitive Automatic Single Spring Greenhouse Window Vent Opener

The instructions say, fits with supplied screws or clamps, but clamps are not supplied. Misleading.Therefore it didn't fit my greenhouse. But after drilling a few holes etc. I managed to fit it and it works fine. Cheap n nasty looking but, for the price, good value.

sorry my husband is still trying to install - he is up the ladder again at the moment

Functional, well made design - easily fitted to a wooden framed greenhouse, but NO clamps included for an aluminium frame. You will need to purchase suitable clamps, or be prepared to drill your aluminium frame and use self-tapping screws.

Works very well easy to install and set up

Bought for husbands greenhouse, easy to install and good quality. If my husband can install it anyone can

It's fine

Working well made a great difference to my greenhouse.

As was described so quite pleased
