I would never use a bungee cord to hold anything
that could be put under load....such as a door with the wind blowing against it.
it is not IF, but WHEN that bungee cord gives way, breaks, and sends parts
flying...usually into the face of a person or horse. I have a nylon motor cycle
tie, not the ratchet type, but the kind you pull the end tight, and then push
down to release that I have used to hold open a door. But never a bungee.
I also never, ever use the bungee ties that folks think are designed to tie
horses. I've seen them break when a horse pulled back, and sent a snap flying
through the air like a missile.
