Box, I-Beam, and Torpedo Levels
Level up! Levels are built using three primary designs: I-beam, box and torpedo. Though I-beam and box often look similar and enlist a bubble or spirit to determine surface level, they are not the same tools: box levels are used on a variety of surfaces, while I-beam levels are designed to determine the trueness of I beams in construction. Built smaller, torpedo levels are designed for use in tight spaces. In addition to I-beam, box and torpedo levels, you can also find magnetic torpedo levels and laser levels. Additional categories to browse include rotary and straight-line laser levels, specialty levels such as master levels, laser level accessories, leveling rods and tripods.
