The guide has two perpendicular legs equipped with flanges for aligning the guide and directing a hand tool along the guide. Measuring units are provided along surfaces of the guide to allow it to be used alternately as a carpenter's square and to facilitate carpentry operations without premeasuring. The flanges are shorter than the legs to provide cutouts for clamp removal and a cross brace enables the guide to be optionally stabilized without clamps. | |
