�� <br /> UNION <br /> ����� <br /> 3...4...S...Triangle Method <br /> Z <br /> Usi�g two tape measures,locate point C by hooking <br /> one tap to a nail at point A and the second tape to a <br /> � nail at point B.6ctend the tapes until they cross and <br /> � 4 5 meet at 4'on the first tape and 5'on the second tape � fi " <br /> and place a temporary nail where 4'and 5'meet. <br /> 4 ...the 4'and 5'measuremenu are <br /> ; the 4 and 5 sides of the 3...4...5... <br /> triangle. <br /> � 3 � <br /> �t <br /> � 2 <br /> 2 <br /> . <br /> ._ <br /> 1 � <br /> '• : <br /> ' ' _ .;�:�,�,,� <br /> 1 3 �_�_u:_.,,_,.=K <br /> 1 Establish a line from point A to point B by <br /> temporarily marking each point with a nail. <br /> The line must be paraliel to the eave and in <br /> this example 3'long(this is the 3 side of the <br /> 3._4_.S...Triangle). NOtE: <br /> � For larger 3._4._S...Triangies muitiple <br /> each side of the triangle by the desired <br /> increase in size. For example,if the roof <br /> panels are 25' from eave to ridge, <br /> multiply each side by a factor of 6 for an <br /> 78:_24:.30'_.Triangle. Obviously, the <br /> �� � � closer the triangle vertical leg length is <br /> to matching the panel length, the <br /> greater the squaring acwracy. <br /> _� <br /> . <br /> � 3 � <br /> � �, <br /> Hook a chalk line to point A and pull it in <br /> line with point C and mark a chalk line on <br /> the roof deck <br /> This will be the square reference line for <br /> �� the MasterRib�panei installation. <br /> � <br />
