The DeWalt self-leveling cross-lines and plumb spots laser provides accurate plumb point transfer by projecting two bright horizontal and vertical self-leveling beams. Made with a durable over-molded housing, the tool is resistant to water, debris, and harsh outdoor conditions. The locking pendulum mechanism also protects the internal parts from damage. The integrated magnetic pivoting base, featuring front- and rear-mounted magnets, enable you to attach the device to metal tracks. Thanks to its full-time pulse mode, the tool is compatible with a detector.
