Each of the three chambers holds three standard deep frames (9-1/8 inch), meaning you can use frames you already have on hand. Bottom board has three entrances; the one in the middle opposite the entrances on the ends. Dividers in the deep box go to the bottom. An additional 3/4” space at the bottom allows for inserting frames with swarm cells. Inner covers feature a notch at one end (to be positioned opposite the entrance).
Feeder holes accept a Boardman feeder cap (not shown but included).
Requires a standard sized outer cover, sold separately.
