Abstract: A precision level is the type that has a level indicating means and is turned end for end to determine the amount one point on which the end of the level rests must be changed in height with respect to a point at the other end of the level to have the points on a horizontal line. A mounting through one end of the main body of the present level positions a conventional differential dial indicator above a foot that is adjustable in height, and the sensing stem of the indicator follows the upper end of the foot to show the amount the points must be changed in height to position the points on a horizontal line. For levels of different lengths, sections for the main body are connected together. Latching assemblies for joining the sections have hook-shaped members mounted on eccentric pins, the pins being rotated to pull the sections tightly together.
