The extra-strong neodymium (rare earth) magnet will firmly hold your GAMMON REEL® plumb line reel and position your plumb bob 3 inches from any steel surface. (We have also provided a handy nail sleeve for use on wood surfaces.)
The GAMMAGNET® magnetic case allows you the flexibility of using your GAMMON REEL® plumb line reel by itself or enclosing it in the GAMMAGNET® magnetic case as needed.
Plumb line reel and plumb bob sold separately.
