Abstract:
A border measurement system for use with a suspended grid structure, and for establishing a specified distance between a wall angle and a plurality of engageable cross runners, said system comprising:at least one main runner defining, in cross section, a tile support lip and a web extending from said support lip, a plurality of elongated channels being formed through first and second opposite faces of said web at axially spaced apart intervals and between a first end and a second end; the plurality of cross runners extending between first and second selected main runners, each of the cross runners also defining, in cross section, a tile support lip and a web extending in substantially perpendicular fashion from a midpoint of said support lip, first and second connector clips extending from associated first and second ends of each of the cross runners and engaging, in laterally inserting fashion, through aligning channels defined in said first and second selected main runners, and a measurement indicia scheme being applied to at least one exposed end border portion of each of said main runners and extending inwardly from said at least one exposed end border portion a limited distance, which is less than an overall length of each of said main runners, said indicia scheme including equally spaced and incremental markings coinciding with the placement and location of at least a first of said elongated channels positioned relative said main runner end, said indicia scheme further establishing a defined distance from a second and succeeding elongated channel, said first and second elongated channels corresponding, respectively, to primary and secondary reference points proximate said extending end of said main runner, said primary reference point being located a first measured distance from said main runner end, said secondary reference point being located at a succeeding and greater measured distance from said primary reference point, said measurement scheme being employed, upon selection of one of said primary and secondary reference points, to establish a correct border distance of said main runners for sectioning and prior to location of said cross runners and engagement of said connector clips within said main runner channels and so that equal borders are established along opposite extending ends of a room enclosure within which the grid structure is installed.
