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.

Abstract: A utility vacuum that may be configured to employ a disposable bag or removable and reusable container for the collection of dirt and debris that are drawn into the utility vacuum. The utility vacuum may employ one or more movable legs that are movable between an extended position, which provides relatively stable operation of the utility vacuum, and a retracted position, which reduces the footprint of the utility vacuum so that it is easier to store.

Abstract: A multi-purpose strap for use with a laser tripod having a head portion and a base portion includes a flexible member, a first coupling component located at an end of the flexible member, and a second coupling component located at an opposite end of the flexible member.
