The ornamental design for an extensioncord with lengthmarkings, as shown and described.
FIG. 1 depicts a front perspective view of an extension cord with length markings showing my new design;
FIG. 2 is a front elevational view of the extension cord of FIG. 1;
FIG. 3 is a rear elevational view of the extension cord of FIG. 2, which is rotated upwardly by 180°;
FIG. 4 is a top plan view of the extension cord of FIG. 2, which is rotated downwardly by 90°;
FIG. 5 is a bottom plan view of the extension cord of FIG. 2, which is rotated upwardly by 90°; and,
FIG. 6 is an enlarged perspective view of the identified portion of the extension cord of FIG. 1.
As shown in the accompanying drawings, the extension cord with length markings includes a pattern of markings that repeats every 16 inches. In the figures, the extension cord is shown with symbolic break in its length. The appearance of any portion of the article between the break lines forms no part of the claimed design. The breaks in the drawings indicate, for ease of illustration, that the precise overall length of the extension cord with length markings is not claimed. In the drawings, the broken lines depict environmental subject matter only and form no part of the claimed design.
