With each compartment holding one gallon, this two compartment feeder sits on top of the hive boxes, just under the inner cover. Bees access the feeding area through an open slot that runs cross-ways in the middle. After syrup is poured into compartments, slow-to-sink pine slatted floats can be placed on top of the syrup, preventing drowning. Click here to purchase 10-frame slatted floats by the pair. Or you can choose screen to cover the center bee slot and allow bees to suck syrup through screen holes. The bottom is recessed 1/8” to minimize rocking on burr comb left on the top bars of the box below it. When we assemble, seams will be caulked to ensure that it is leak-proof.
