We have found that these ring magnets are often used by customers that need a magnet to go over a pipe or string.

The diameter of the overall ring measures 40 mm (1.58in./4cm.). A perfect size if you need want to pass a piece of string through it and collect a heavy bunch of keys dropped in a sewage grate. Or if you need to “fish” out metal materials from a sprinkler tank or loose nuts/bolts dislodged throughout a car/truck engine bay.
