Designed for use with the #012 GAMMON REEL plumb line reel in steel frame and steel beam construction.
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.
NOTE: Plumb line reel and plumb bob sold separately.
