I want to put a port, covered hole of some kind, in my tent wall about 4 to 6 inches up from the floor in the back right corner for an extension cord to pass through. I would like it to seal up (kinda) to keep bugs out. any good ideas or products i should look for ? cutting a hole in a tent is crazy to me, but i like the idea of having a port to run a cord and/or propane hose, coax cable .....out of the tent without going out the front door.
