Hi Keith,
The RV Designer Round Low-Profile Cable Hatch part # RD46GR fits into a cutout that is 3 1/2" in diameter. The overall flange dimensions are 4.6" x 2.6". You may need to enlarge your cutout for it to fit if it's too small. The snap-on lid will make it easy to access your cables to hook up to the shore station and fits up to 50-amp power cords.
What are you intending on running through the hatch?
