All our hive bodies are made here in our woodworking shop. We use the best American pine available. over the years we continue to add new machinery to provide even better cuts and joints. We make every piece by hand and know the quality we produce is the best in our industry today! We cut our joints to be a tight fit. This reduces the amount of moisture that can enter the joint once assembled and thus prolongs the life of your equipment. Commercial grade shallow super. No nails included. Uses 5-3/8" frames. (frames and nails not included) Made from white pine.
