Keeping residential fridge doors closed during travel

I have been in the RV industry for 33 years.
How do you keep the residential fridge doors closed during travel.
I have been asked this question many times.
I believe you can use magnetic strip tape.
Found at most arts & craft stores, or hardware stores.
Put the strips horizontally on each door.
When you reach your destination.
You can just stick them to the door,
or side of the refrigerator.
