Automatic Shelter Vent Kit, model #11300. This new and
improved vent kit has a heat-sensitive spring that automatically begins opening the vent at 74°F (23°C), to be fully openned at 104°F (40°C). As the temperature drops, the vent closes automatically as well. In addition, the vent has screens that will keep out insects and debris. The AutoVent works great with any fabric-covered “instant” garage or storage shelters.
Each vent kit includes two durable injection molded vents with Hi-UV protection and weather resistant resins
Pre-drilled holes for easy installation-hardware included
