The Johnson Level 10" Big J® Magnetic Torpedo Level is the heavy-duty workhorse for electricians, plumbers, and HVAC pros who need reliable leveling on conduit, pipe, and metal surfaces. The oversized solid aluminum frame with machined edges provides superior durability and accuracy, while powerful rare-earth magnets deliver 3x stronger hold on ferrous materials for hands-free use. V-groove fits round pipe and conduit perfectly, and three high-visibility vials (plumb, level, 45°) ensure readings in any position. Oversized 1/2" vials are easy to read from distance—your essential for rough-ins, installations, and tight-space work that demands jobsite toughness and precision.
