through wall A/C hookup?

[Poorlytiedfly]

What should I be looking for regarding installing a "port" through a wall where I can hookup A/C? I am sure there is some sort of weather resistant port where I can hook up a 3" or so flexible duct.

any suggestions?

ClimateRight sells those to go with their small air conditioning units. If you don't want a ClimateRight air conditioner, you can still buy the wall hookups separately, I believe. https://climateright.com/air-conditioning-heating-5.html

Many people use "deck plates". Take a look at this thread: http://tnttt.com/viewtopic.php?f=30&t=44561.

I'm confused. You talking air conditioning, or shore power AC?

If the former, you mean for a trailer, with the whole unit outside, and only the cool air comes into the living space through a 3" air duct?

If so, please link to an example such unit.

If you mean a shore power cable, here's a quick & dirty example, Google​Promariner 51202 Universal AC Plug Holder

I used marine deck plates

What is that unit in the bottom pic?
