Keep your queen out of your honey supers. These are a must if you plan to produce comb honey. The openings are perfectly spaced.
Also works well on our 10-frame Polystyrene hives.
i keep coming back to Blue sky because of the quality of the products they sell.
Well built. Excellent product
This is my third order of these excluders. I do sell some supplies but these excluders are reserved just for my use.
The profile cannot be made any better. Spacing is superb and setting them out is simple since either face gives you the same spacing.
