Disclosed is a combination rule, horizontal level, vertical plumb and straight edge. By use of two parallel scales running reverse to one another mounted to an elongated member, direct read measurements can be taken between two points up to a distance equal to twice the overall length of the tool such that no arithmetic computation is required. Perpendicularly mounted target levels allow the tool to be used as both a vertical plumb and a horizontal level. A flanged box beam member provides finger tip recesses for easy manipulation and maneuvering of the tool by the user.
