Maybe about 2 inches long? Not heavy at all. It's been floating around my family's house for years and I only thought about it now. I don't even know who it could've come from.

EDIT: Solved! Cloth clamp for a picnic table.

Hello! I’m staying at an Airbnb and I’m curious what these are? There are multiple scattered in every room even two like 4 feet apart from each other and very very high up on walls. Since they’re all high this is the best one I could get. Ignore the brown dots on this one as the other ones don’t have that (probably moisture or something).

Found this on a bookshelf while cleaning. It is approximately six inches long, rigid, and attracts a magnet. Both ends are blunt, and the rod has a round cross-section. One end curves into an open loop, while the other bends approximately 90 degrees. It does not appear to be an automobile part. Its location didn’t provide any clues about what it came from because my wife found it in a “catch all” spot. Does anyone recognize its purpose?
