This is a specialty item from Swienty, our favorite bee gear maker in Denmark. It offers all the advantages of the 10 frame feeder, but holds a little bit less syrup. An easy, non-invasive 8 frame feeder that minimizes drowning. Bottom photo shows the feeder being used with our Vivaldi Board, which features an additional ventilation hole to keep air flowing when the feeder is in use. May also be used in a 10 frame hive. Pairs perfectly with our 8 frame Vivaldi inner cover (sold separately).
