We found plastic trays sold as floor protectors (available in two sizes) for under Christmas trees work great to cover our bin inlets when fans are not in operation. In the winter, they keep snow and sleet from freezing on the fan blades, which can cause fans to get out of balance and create premature failure. In the summer, they prevent insect activity under bin floors by disrupting warm airflow into that open area. The protectors also prevent wind from causing the free-wheeling fans undue wear year-round.
