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

Very happy with ACF for having the replacement in stock. The original lasted about 6 years.

I purchased the Univent replacement power tube. I received it fairly quickly and it works great.

Units arrived in great shape and very quickly. They fit our units and work perfectly! Would recommend ACF Greenhouses - nice people and they know their products. Will certainly use them again!
