Gatco - Model Vent-A-Lid - Ventilation Tool for Grain Bins
No more opening and closing lids with the weather. The Vent-A-Lid is a specially designed ventilation tool for your grain bins. By installing the Vent-A-Lid on your existing lid, you are creating ventilation at the highest point of your bin, where heat naturally wants to flow. The Vent-A-Lid is designed with a deflector that nearly eliminates snow and birds entering your bin while allowing ventilation at all times.
