This is my first Kenyan top bar hive design. The interior length is 38-1/2" with allows for 30 bars; twelve 1-1/4" wide Brood bars, four 1-3/8" wide Drone bars, and twelve 1-1/2" wide Honey bars. There is a long viewing window on one side with a removable cover panel. The entrance is a slot, 3/4" x 5" on the front end. The gable roof is removable and ventilated along the soffits and at the gables. I am planning on using a rubber bungee cord between two latches on each side to hold the roof in place from being dislodged by wind or bumping. The bottom is screened with #6 hardware mesh for ventilation and to allow mites and debris to fall through. I have designed top bar with a T support, using a 5/8" dowel and a 1" wide bottom bar instead of just a plain top bar.
