The Improved Mann Lake Top Feeder Insert features a galvanized steel safety screen designed to reduce bee drowning.
 
This top feeder is constructed of heavy-duty, single-piece plastic to provide a no-leak reservoir! The painted wooden surrounding measures 4½" × 19⅝" (11.43 cm × 49.85 cm) and fits all standard beekeeping equipment. There is no comparison to the strength and durability this hive top feeder provides over foam top feeders.
 
With this setup, your bees can access their food through a barricade and steel safety screen to keep them secure. Save time with a high-capacity feeder for apiaries that holds 4 gallons of bee food for the 10-frame option and 3.2 gallons for the 8-frame one.
 
Benefits of a Hive Top Feeder:
Fill the feeder without opening the hive
One-piece construction prevents leaking
Painted wooden surrounding measures 4½" × 19⅝" (11.43 cm × 49.85 cm)
 
Remove honey supers intended for human consumption prior to feeding.
Pro Tip: If this feeder runs completely empty or the syrup level gets very low, bees may crowd under the screen and struggle to find their way back, which can lead to drowning. To help prevent this, you can apply a bead of food-grade caulking along the bottom of the screen.
