I had an existing vent hole in my battery cabinet of my 4Wheel Camper. I wanted to set this up as an option to have 鈥渟hore power鈥 in my camper, or to add a battery charger to my lithium battery. They were accurate with needing a 2 inch hole. I have very thick walls in that part and the extension cord comes off at a 45掳 angle on the inside wall portion so I had to drill a bit of a groove for that cord to fit into. The weatherproof gasket they provide, the tight fitting rubberized electrical port cap, and the overall construction is fantastic.
