Recommended with the installation of any binnacle mount compass on 6-7/8" (Edson Series 300) pedestals, this plastic weather shield mounts underneath 5 inch compasses.
It functions as a gasket, and helps prevent water from infiltrating into the top of the pedestal, or below decks through the pedestal.
Outside diameter 7-1/16"
Use with 5" binnacle mount Globemaster compasses
Use with 4-1/2" Navigator compass (DNx-200), as it has the same mounting hole pattern as the 5" Globemasters
