It uses ultra-strong neodymium magnets to locate and hold the drop magnet through wall cavities, helping installers guide cable paths with fewer access points. The wire pulling magnet features a patented radial leader magnet design that requires only a 3/4 in opening for setup. Its drop magnet includes a pull line, an eyelet for attaching wire or cable, and a stainless steel housing that supports corrosion resistance during repeated use. The magnetic retriever has a two-wheel design that moves efficiently along walls, with rubber-coated wheels to help prevent surface scuffs and wall damage. An ergonomic plastic handle with finger grooves supports comfort and control during cable routing work. The system includes the magnetic retriever, drop magnet with pull line, and a hard plastic carrying case with a handle for storage and transport. Covering by multiple patents, the system combines strong magnetic holding power with surface-safe handling. For installers working in hard to reach places, The Jonard Tools MP-400 MagneTriever® MaxForce Magnetic Wire Puller provides a practical cable retrieval solution.
