This solid bottom Pine Jnuc is the same as our screened bottom White Pine Jnuc, except this one comes with (3/4" Pine solid bottom with a 4" wide by 1/2" high opening in the front. for the wedge to reduce or close the entrance. The top is made from 3/4" MDO plywood and does not come with a feeder hole. Our boxes have 7/8" deep frame rest for an extra 1/4" above the frames to make it easier to put in Queen cells or adding feeding patties. Comes with 2 handles for easy pickup and this box will also make a great Swarm Box. Also take a look at our 5 Frame Castles for making splits.
