ABSTRACT:
A means of gridded measurement for the cuing of construction materials which comprises the imprinting of commonly used measurement markings upon the surfaces of construction materials during the manufacturing process to save time and improve the accuracy of cutting the construction materials on a job site. Unit markings may be numbered for quick dimensional reference and fractional markings may also be used. The lines for commonly used markings may also be highlighted, darkened, doubled, tripled, dashed or dotted, and color enhanced for easy recognition. Applications may include, but are not limited to, use on wallboard, shower board, insulation, gypsum board, plywood, and any other material which must be cut to exact measurements on a construction job site. Angled cuts may be easily made by cutting along the opposite corners of a predetermined number of grids counted in both horizontal and vertical directions.
