This approach is certainly satisfactory, but it is also the most expensive since it requires thirty frames instead of twenty. Frames and Combs. The suspended comb is the basic structural component inside the hive. Each comb is composed of a wooden or plastic frame that supports a sheet of comb foundation. After the workers have added wax to draw out the foundation, they use the cells for storage of honey and pollen and for brood rearing.
Frames come in sizes to fit the various hive-body depths.
Each frame consists of a top bar, two end bars, and a bottom bar. Top bars are suspended on ledges or rabbets in the ends of the hive body. Metal strips in the shape of an acute angle or frame spacers are often nailed on the recess for reinforcement. The shoulders on the end bars may also help hold the frames apart. The comb foundation consists of thin sheets of beeswax imprinted on each side with patterns of worker-sized cells.
