Keeping residential fridge doors closed during travel

huh, over 15 years travelling and none of my fridges ever opened.

when I get set up, I SLOWLY open fridge to see what might jump out.

but nothing ever swung my door open. what ya carrying in there :) :)

I saw those extension poles that go across from side to side (like curtain rods) in the fridge to keep things in place but I never had to buy them.
