Nice video. This is an interesting approach and quite compact. Another option if you want to keep the magnetic seal with a wooden collar is to stick some strips of metal onto the wood where the door seal touches.
Thanks so much, I have the brew bucket by SS brew-tech and is about 20 inches because of the short legs. I would be using a blowoff hose so it looks like I should have plenty of room. Can you give me the height from the floor of the fridge to where the freezer starts. That should give me the height I need. thanks again and a great video.
