If you've enlarged your Trio house Compartments from the standard 6" X 6" floors to the roomier 6" X 12" that martins prefer, these blank replacement doors can be used to close off the back compartment entrance. Fits all Trio models sold by the PMCA. Will not fit other models or brands.
These blank doors do not have the louvered vents. Doors with louvered vents are currently not available
