This external bee feeder can be used on the Ultimate Hive Cover, where a push out hole has already been placed for the feeder or you can drill a hole in your outer cover. The location of the feeder makes checking the feeder simple without needed to open the hive. It features a nipple and a twist lock to make feeding quick and easy. The one-gallon capacity allows you to feed less often. This feeder comes with a cap to close the hole in your outer cover when not feeding.
