    I picked up two last year on a whim because they were on offer (2 for 20). Hoped to use them on the tunnel but was afraid of wind damage. Still toying with ideas but was thinking of using them on a homemade cold frame, but I would put them at the sides. That way you can still open the top lid. Or else make a mini-hoophouse type with timber panels on either end with a window and vent opener on each. The whole thing then could be lifted up or hinged for getting at the plants underneath.

    I think the autovent is a none runner as vc said it is attached to the frame and the lid so difficult to access the cold frame. The louvre opener may work but bear in mind the piston opens up the way.....does the lid or does it angulate as it opens..........is angulate an actual word?

    You could put a louvre window in the side panel and let that open automatically, leaving the lid to be opened manually.
    Angulate is a real word - must be your NHS background or..... do you like tortoises? (I had to look it up too)

    Andy I found your post when doing a vine search on building a coldframe so thought I'd share this link :-

    on the second page he's fitting an auto opener.

    That's good Bren but how do you open the lid if the lid isn't open?......Those springs are quite strong.

    As BM says ^^^. Also, even on hot days, the window doesn't open very wide, so putting plants in and out and watering would be nigh impossible. On cold days, it would be completely impossible without removing the auto opener and you couldn't do that because its screwed to the inside of the frame.
