2 Piece Purple Martin Gourd – 4 Pack

If you’ve enlarged your Trio house Compartments from the standard 6″ X 6″ floors to the roomier 6″ X 12″ that martins prefer, this blank entrance door can be used to close off the back compartment entrance. The replacement doors fit Trio Castle, Mini-Castle, Musselman, Grandpa, Grandma, and Wade.
