The medium frame is used inside a Medium box in the hive. Medium boxes will have 9-10 frames inside the box with or without a foundation.  The frame allows for spacing and a support for the comb that the hive will build.  The medium frame is assembled with a beeswax coated foundation and ready to use in your hive.  Use in starting a new hive or replacing existing damaged ones.
