Polytunnel Roll-up Side Hand Winder Winch

These winches, when connected to a roll pole, allow the sides of your polytunnel to be rolled up or down and can be locked off at the height you desire. This allows you to let heat out of your tunnel or keep it in.  

Depending on the crop you're growing and the season, they are not only good for heat control but also for allowing air/wind in through the side of your tunnel or keeping it out on windy days to prevent stress to your crop and reducing condensation in your GROW Tunnel.

By installing insect mesh along the sidewalls of your polytunnel or greenhouse you can keep the bugs out but still allow the air flow to pass through from the side. 1 x manual roll up winch will operate up to 49M in length.
