Abstract:
In combination, lumber having a predetermined width and a construction tape having a width, thickness, indeterminate length, and features designed to locate or measure repetitive positions for said lumber through said indeterminate length, wherein the improvement comprises a marker repetitively printed upon said tape having a center region which has a length parallel to said construction tape indeterminate length that is equal to said predetermined width of said lumber and which operatively defines a desired lumber position, said marker comprising:a first visually converging region immediately adjacent said center region which has a width equal to one-half of said predetermined width of said lumber and which converges as a distance from said center region decreases; a second visually converging region immediately adjacent said center region which has a width equal to one-half of said predetermined width of said lumber and which is spaced from said first visually converging region along said indeterminate length of said tape by said center region, said second visually converging region converging as the distance from said center region decreases; a line transverse to said indeterminate length which divides said center region into two equal parts; and a diamond subdividing said transverse line into two equal parts.
