This is a #ventilated #beehive topper #Quiltbox used for ventilation to reduce moisture. It has a hole for the bees to gain access to the #brood box. Also in the back you can open without breaking the #propolis seal completely to feed #pollen patties directly on the top of the frame or even check on the bees if needed. YOUR INNER COVER IS NOT USED WITH THIS. After installation, put wood chips inside to box to reduce moisture. It helps fight moister/condensation problems. If you open your top cover and see any water & or looks wet, you have a Huge problem! As the #bees must stay dry. Winter times in colder states have issues with wet bees dying..This is usually association with poorly ventilated #beehives. This topper box will help..
