In the layout of the location of studs for wall framing a template is provided to eliminate the tedious, time-consuming and oftentimes inaccurate procedure of using carpenter's squares, rules and the like with accompanying pencil marks. The template uses a number of blocks slidable along a blade provided with a rule scale, each releasably held in place by a thumb screw. Each block has a pair of parallel cutting edges for scribing the stringers thereacross by the simple expedient of tapping the blocks with a hammer, such that, during assembly of the framework, each stud need merely be held between a pair of marks inscribed into the stringer while nailing the stud in place.
