Position and angle indicating tool

Abstract

Position and angle are measured by a linear device having an elongate frame comprising a pair of parallel arms joined by a cross-arm, each of the arms terminating with an adjustable foot so that the device may be leveled, thereby establishing a level reference platform from which position and direction may be determined. A support bracket is adapted for rigid engagement with the elongate frame and is linearly positionable on it. A laser beam source is removably engagable with the support bracket for positioning a laser beam in a selected and known direction. The feet are spaced for clamping the T-bar sections of a dropped ceiling so as to enable the placement of further T-bars, roof joists and other structural members at selected angles. The arms provide parallel, spaced apart grooves for mounting the apparatus onto the T-bars.
