A marking system incorporated into a cross runner for use in a suspended grid structure extending within a walled enclosure, the grid structure supporting a plurality of ceiling tiles. A plurality of main runners are suspended from a ceiling of the enclosure in parallel, spaced apart and elongated extending fashion. Each of the main runners define, in cross section, a tile support lip and a web extending from the support lip, a plurality of elongated channels further being formed through first and second opposite faces of the web at axially spaced apart intervals and between first and second ends. A plurality of interconnecting wall angles are secured to selected surfaces of the walled enclosure, each of the wall angles having an elongated body which includes, in cross section, a first side and a second side extending from an interconnecting edge with the first side. A plurality of cross runners extend between a selected wall angle and a selected main runner, each of the cross runners defining, in cross section, a tile support lip and a web extending in substantially perpendicular fashion from a midpoint of the support lip. At least one of first and second connector clips extend from associated first and second ends of each of the cross runners. A marking indicia is applied at selected intervals along each of the cross runners and is capable of identifying, upon positioning of the cross runner, a correct linear and measured distance between the selected main runner and selected wall angle, an end portion of said cross runner capable of being sectioned prior to inserting engagement of a selected and remaining connector clip with the selected main runner and abutting engagement of the sectioned end portion with the wall angle.
