Johnson's durable & accurate 24" digital box level is the perfect addition to your toolbox. Its "EZ-Read" backlit display is highly visible on both the dimmest & the brightest jobsites, while the digital measurement reading will automatically invert for convenience when you are taking overhead measurements. This level can show five units of measurement - degrees, percent, in/ft (fractional), in/ft (decimal) & mm/m - & has an accuracy of +0.1° at 0°/90°. Durability is also never a concern with this level - its rigid box frame resists deflection & twist, shock-absorbing end caps protect the level when it is dropped & the solid block vials were designed to never fog, leak or crack. It comes with a soft-sided pouch to keep your tool clean & safe when not in use.
