The Mag Kit Magnetic Strap allows technicians to keep their hands free and their tester safe from potential drops and accidents. The strong rare-earth magnet allows the meter to be attached to a variety of magnetic surfaces. When working with surfaces that are not magnetic, the technician can easily hook the strap onto a J-hook using the hole in the strap. The strap can also be folded to provide a sturdy stand for your meter should the need arise.
