Deep Pro Division Board Feeder Holds 1 gallon (3.78 l) Ear measures 2" (5.08 cm) Fits snug using 9 new frames Stronger: The wood cap system and the inside wall supports add to the unparalleled structural integrity of the feeder. Revolutionary Cap & Ladder System: Sealed feeding tubes ensure the bees are confined to the feeding area so you will experience minimal drowning. Easy To Clean: This is the only feeder available where the entire cap and ladder system is easily removed for cleaning. No Burr Comb To Clean: Sealed feeding tubes prevent the bees from making burr comb in the feeder and keep the queen from laying brood inside. Textured Interior Wall: Textured interior walls for those who wish to use the feeder without the cap and ladder system. New & Improved Ladder!: We've completely redesigned the ladder using better material and adding a lip at the top and a flat bottom to hold it in place better.
