Versatile measuring device

摘要: An improved versatile measuring device for linear, and angular dimensions defining relative positional parameters or coordinates between a plurality of lines, points, surfaces on plane determining duplicating line lengths positions any number points surfaces. The has protractor members each which is rotatably clampably attached to connecting member itself linearly extendible may also be altered have pivoting point about main arm an the are pivotal clampable with respect other. Each ends edge-guide slot substantially parallel scribe edge. Slideably mountable onto slots at least one pin positionally adjustable securable within slot. pins provide edge reference useful repeated consistent layout marking article such as stair stringers roof rafters being prepared use.
