<p>A measurement indicia scheme applied to a main runner (18) of a suspended grid structure to establish a correct border distance of the main runner (18) and between an associated wall angle (19, 19') and interconnecting cross runners (12). The measurement indicia scheme is applied to the main runner (18) and extends from at least one of the first and second ends of the runner. The indicia scheme coincides with the placement and locating of at least a first of the elongated channels (32, 34, 36, 38, etc) positioned relative the selected and main runner end. The indicia scheme further establishes a defined distance from a second and succeeding elongated channel positioned along the, main runner (18). The first and second elongated channels correspond, respectively,to primary and secondary reference points proximate the extending end of the runner, the measurement scheme being employed, to establish a correct border distance of the main runner (18) for sectioning prior to location of the cross runners.</p> |
