NdtE: <br /> For Iarger 3w4.S...Triangies multiple <br /> ; ` each side of the t�iangle by ihe desired <br /> increase in size. For example,if the roof <br /> paneis are 25' from eave to ridge, <br /> multiply each side by a factor of 6 for an <br /> 18'_24:.3�Triangle. Obviously, the <br /> �� closer the triangle vertical leg iength is <br /> to matching the pane� length, the <br /> greater the squaring accuracy <br /> � 3 <br /> � <br /> � <br /> � <br /> Hook a chalk line to point A and puN it in <br /> fine with point C and mark a chalk line on <br /> the roof deck. <br /> Tfiis will be the square reference line for <br /> �� tfie MasterRibm panet instaltation. <br /> � <br />
