The Retriever component of the LSD85-124 is a flexible, insulated 24" handle with a neodenium magnet attached to one end. This rare earth magnet, unlike an alnico magnet, will not lose its magnetism if it is hit. The "Wet Noodle" consists of 10 feet of .090" (half the size of a regular ball chain) smooth nickel plated steel ball chain, a "stop ring" that will prevent the chain from falling through the drilled hole, a #6 in-ring connector to pull the wire and a #3 "b" coupling to attach a second chain if needed.
