Polytunnel Door Openers
Posted: Mon Oct 15, 2007 3:56 pm
Hi, Anyone come across a thermastatic Polytunnel door opener?
I use Bayliss Autovents in the upper half of each door which is a pivoted frame. It is rather expensive as the cylindrs tnd to fail after a few years and one really needs the hydraulic vent openers if there is much wind. I have platic mesh on the bottom half of each door, covered in wnter with a polythene blind and metal mesh at the very bottom to defeat rabbits.
