BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates generally to cross tee members utilized in a ceiling grid assembly. More specifically, the present invention is directed to a two- or four-foot cross member incorporating a measurement scheme specifically tailored to account for a dimensional offset existing between an associated end of a cross tee and a center point of the main tee measured to an oppositely positioned wall angle. [0003] 2. Description of the Prior Art [0004] Suspended structures for creating ceiling grids are fairly well known in the art, the concept behind such structures being to provide suspended support for ceiling tiles. The tiles are typically rectangular shaped and acoustically insulating in nature and function to recreate a uniform and "dropped" ceiling appearance to an interior enclosure with an unfinished ceiling, such enclosures including commercial building interiors, as well as basement ceilings in residential dwellings. [0005] U.S. Pat. No. 4,677,802, issued to Vukmanic, discloses one known arrangement of suspended ceiling system and runner and which is characterized by each of the runners being composed of a first member and a cap member. The first member is bent to form an inverted T-bar configuration with a groove extending inwardly from the flange of the T and the cap member having the same configuration and being secured on the flange of the T-bar configuration to form a channel with flange portions on each side for supporting panels of the ceiling system. [0006] U.S. Pat. No. 4,712,350, also issued to Vukmanic, discloses a centering arrangement for T members of a suspended ceiling for holding a plurality of panels supported by the runners in a desired position on the flanges of the runners. The centering arrangement includes a bump extending from each side of a cross-sectional web profile of the runner, the bump being formed in the web immediately adjacent a cut in the runner so that the drawing of the material into the bump will not draw material from the flange or adjacent thereto. The bump shape is preferably "half-moon" or semi-circular in configuration and so that it provides a smooth camming surface for both lateral movement of the panel along the flange as well as vertical movement towards the flange. [0007] U.S. Pat. No. 4,525,973, again issued to Vukmanic, teaches a suspended ceiling system again teaching main runners and cross runners which are inter-engageable to define a rectangular grid system. Suitably configured and elongated apertures are formed in the webbed profile of the main runners in axially spaced apart fashion and which receive an appropriately configured connecting end of selected cross runners and so that the cross runners are engaged to the main runner in mutually engaging fashion and on opposite sides thereof. [0008] U.S. Pat. No. 6,477,815, issued to Paul et al., teaches a suspended ceiling grid structure with main runners incorporating a coded matching indicia for receiving cross runners in a desired spaced apart fashion. Of note, the marking indicia is applied to selected channels of the main runners and identify proper location of the cross runners prior to engagement of the connector clips within the main runner channels. The marking indicia may further include coding selected channels according to at least one-color indicia. [0009] Finally, U.S. Pat. No. 6,526,716, also issued to Paul, teaches a suspended ceiling grid structure with main runners incorporating measurement indicia for establishing a border dimension for engagement by a cross tee. The indicia scheme is applied to the main runner and extends from at least one of the first and second ends of the runner. The indicial scheme is applied to the main runner and extends from at least one of the first and second ends of the runner. [0010] The scheme further coincides with the placement and location of at least a first of the elongated channels positioned relative the selected and main runner end. The scheme establishes a defined distance from a second and succeeding elongated channel positioned along the main runner. The first and second elongated channels correspond, respectively, to primary and secondary reference points proximate the extending end of the runner. The measurement scheme is employed, upon selection of one of the primary and secondary reference points, to establish a correct border distance of the main runner for sectioning and prior to location of the cross runners and engagement by the connector clips, associated with the cross runners, within the main runner channels. SUMMARY OF THE PRESENT INVENTION [0011] The present invention discloses a measurement scheme applied to a cross tee member and which accounts for an offset between the tee and a cross-sectional center point of a main tee measured to a wall angle. As will be further explained, the present invention makes possible quick and easy sectioning of a portion of a two- or four-foot cross tee, and in order to mount the cross tee between an inter-engaging location of a main tee and a parallel spaced-apart wall angle. [0012] As is know, the cross tee is of conventional construction and exhibits an overall length with first and second opposite lip supporting edges. A cross section of the cross tee includes a tile support and a web extending in substantially perpendicular fashion from a midpoint of the support. [0013] First and second connector clips extend from first and second edges of the cross tee. An overall rated length of the cross tee, such as two feet (24'') or four feet (48'') corresponds to a lineal distance measured between center line locations associated with inserting portions of the connector clips. [0014] An indicia marking scheme is applied at linear extending intervals along the cross tee, an outermost selected indicia marking establishing a first specified lineal distance with a centerline location of a selected one of the connector clips. In the preferred embodiment, the first specified distance is one (1''). [0015] The marking establishes a second specified lineal distance with a further selected marking and in order to determine a sectionable length of the cross tee equaling the dimensional offset existing between the main tee and the wall angle. The indicia scheme permits for quick inspection and sectioning of a selected portion of the cross tee, without reference to other measurement tools, and in order to achieve a correct lineal distance corresponding to a remaining (typically less than 48'' or 24'') parallel distance between a wall angle and a proximate and parallel extending main runner.
