Vancouver Island's Beekeeping Supply Store
This Canadian made inner cover will fit the standard 10 frame Langstroth bee hive boxes.
It comes assembled. I has a 2″ hole in the center
It has a deeper overhang so you are less likely to crush bees.
Use with a 3/4″ spacer rim for fondants and pollen patties. It also works well with our Plastic Top Feeders.
