Abstract
A tape measure includes a housing, a rule blade coilable within the housing, and an edge guide coupled to the housing. The edge guide may be oriented in either a first position, in which the edge guide contacts the edge of a work surface, or a second position, in which the edge guide does not contact the edge of the work surface. The edge guide may be permanently or releasably connected to the housing. The tape measure may further include a laser assembly that generates a laser line intersecting the rule blade and the work surface and a calibration mechanism to adjust the alignment of the laser line. In use, the edge guide may orient the tape measure on the work surface such that the laser line is generally perpendicular to the work surface edge.
