Each Johnson Torpedo level is designed with specific users in mind – for instance the magnetic torpedo levels with multi-pitch center vials to read slope in 1/8”, and rare earth magnets (5 X stronger) in rounded shapes so they stick better to pipes – the perfect torpedo level for plumbers. Or consider a torpedo level made out of incredibly durable Structo-Cast non-conductive material, with magnetized V-groove edge to fit on pipes and conduit – the perfect torpedo level for electricians. And don’t forget our Glo-View torpedo level, which glows in the dark, has GripTight rare earth magnets AND V-groove frame to fit on pipe and conduit. Wherever there’s a torpedo level need, Johnson is the torpedo level way.
