An instrument for determining level or plumb orientations includes an elongated body having a plurality of orientation measurement devices. Each of the orientation measurement devices can indicate either a level or plumb orientation depending on a position of the instrument. The orientation measurement devices each include a chamber having front and rear convex sides, a fluid contained in the chamber, and an air bubble floating in the fluid. The elongated body includes a set of first openings and a set of second openings. The orientation measurement devices are embedded into the elongated body through the first set of openings and the orientation measurement devices each include bubble therein viewable from the front and back of the elongated body. The bubble is also viewable from the top and bottom of the elongated body through the second set of openings.
