This metal door sound comes from an episode of Chip 'n Dale Rescue Rangers, the Disney animated series about the chipmunk detectives and their friends solving mysteries. In the show, everyday mechanical sounds were exaggerated for comic effect, which is why this latch has such a clear, weighty clunk. Clips like this later circulated on soundboards as a handy door effect, separate from any specific scene or line of dialogue. Editors still reach for it because it instantly reads as a heavy door opening, even without any picture to explain it.
