A measurement marking and scoring device includes a platform configured to be affixed to a base of a tape measure. The non-planar parting line is comprised of a plurality of peaks and valleys that are offset from the dimple perimeters, as not to bisect any dimple edge. A closure member maintains the distal end in a fixed position relative to the remainder of the wire guide. At least one guide tab depends from the extension downward from the opening, the guide tab being foldable.
