Purchased a Univent / Ventomax Replacement Power Tube on March 8. On March 29 the tube burst and is unusable.

ACF Greenhouses: I'm sorry your power tube stopped working. We will have a replacement shipped out to you right away!

In the past I have purchased whole unit. Didn’t realize I could just buy the part. Installation was easy!

Item was a perfect fit; works exactly as it should.

When putting up our greenhouse, a friend forced open the Univent. In doing so he broke the piston. It was nice to know that they carried a replacement part, and I didn’t have to order the whole vent again. I did not ask them to replace it since it was totally our fault it broke. The part came on just two days.

I spent a lot of time looking for a replacement piston for my greenhouse vent opener; most are too long for my opener and extend several inches when closed. Apparently mine is a Teknic and needs to have the piston with almost no extension when closed, and this one was perfect. Customer service was very responsive in giving me dimensions which allowed me to confidently make the purchase. Thank you
