This hinged frame, that opens like a book, is designed to allow easy capture of feral comb that can then be placed into a conventional hive. Designed by Dee Lusby, it's basically a split frame that is wired on both sides to hold comb in place. Once filled, the ends of the top bar are wired together and placed into a hive.
