Metal Entrance Reducer & Mouse Guard

This tool comes with two side brackets that attach on each side to the entrance of the hive. Once brackets are attached the entrance reducer/ mouse guard piece can be inserted from the top. One side of the reducer is used as a mouse guard and the other side (when flipped over) is used as a reducer to close up the hive for movement and/ or for the winter. This tool can only be used with a standard migratory bottom board. It cannot be used with a reversible bottom board.
