Reversible metal mouse guard. Can be flipped to block entrance with ventilation for moving or remove completely.
Fits a variety of 10 frame bottom board style hives with or without trimming. Mounting brackets are included. Sized large, so that you can snip ends to desired width, depending on your bottom board build.
Much easier to use than other mouse guards and has two opening options or remove when not needed!
Some beekeepers cut notches in the raised portion of bottom board so brackets aren't needed.
