The spacing is 24 inches by5 1/2 foot. The longest comb on the left was 4'9". I filled my bee vac 2 1/2 times (and I mean filled). The vac is the size of a HB although a little shorter. I filled 9 frames with brood. I got the queen from the wallboard that is leaning up to the right. I also got 6 really nice queen cells. I took me 7 hours from unloading the truck until driving away.
