ABSTRACT:
A measurement line marker for the placement of a multiplicity of visible marks on a surface, which marks are accurately spaced from each other by any desired distance, such as sixteen inches on center, and which are located in a straight line so as to provide position marks, such as for the location of studs or other building materials. The marker comprises a thin non-stretchable flexible metal wire, a flexible plastic sleeve thereover having a uniform thickness and having a smooth, non-receptive surface, and a multiplicity of narrow receptive sleeve segments which are spaced from each other by any desired predetermined distances, said segments having a thickness approximately the same as said flexible sleeve and being porous and selectively receptive to marking chalk.
