摘要：A hexahedronic case (12) with a singular face extension (20) and swingout arm pair (14L, 14R) for housing a conventional, flexible measuring tape (26). A carpenter's extensible-retractable measuring tape is housed in a six-faced case which has a pair of parallel, pivotally outward swinging arms and a flange (20) extending from the rear face thereof. Several faces of the case are indexed by marks at the center (24) only of the face edges which have a consistent dimension (Z). On one face, that opposite the flange-bearing face, there is a set of indices (22) which equally divide an edge of the face upon which they appear. The divisions, in respect of the aforementioned consistent dimension, correspond to various pitches or elevations above the horizontal, or angular deflections from the vertical, that are employed in layout work in the building construction field. An example of layout for roof rafter (40) preparation is also presented.
