Designed to be used inside a hive, either on top of the inner cover or directly on the frames (in the fall with a spare box around it), this feeder was designed with function in mind. It features small grooves for the syrup to flow into that prevent bees from drowning. The plastic feeder allows you to see how much syrup remains inside easily and is easy to clean. Holds 1 Gallon syrup. Fits in both 8 and 10 frame hives, an empty medium box is required to surround the feeder to prevent robbing and hold your hive lid. Works with 1:1, 2:1, 3:5 and Pro Sweet.
