While trying to move some file cabinets out of an office space, we had to constantly deal with a door that would not stay open and which was constantly slamming shut because of the wind. At one time, we almost broke the glass.
One of the people helping us grabbed a roll of gaffers tape and unwound about a foot of tape. He wrapped it back on itself, sticky side in, until he had a roll just large enough to wedge under the door.
Instant door stop!
