un��on� <br /> ����� <br /> 3...4...5...Triangle Method <br /> Z <br /> Using iwo 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. Extend the tapes until they cross and <br /> ° e a - <br /> �• 4 5 II meet at 4'on the first tape a�d 5'on the second tape <br /> and place a temporary nail where 4'and 5'meet. <br /> 4 _.the 4'and 5'measurements are <br /> 3 the 4 and 5 sides of the 3...4...5._ <br /> tria�gle. <br /> 3 <br /> � <br /> � ' <br /> � � <br /> 2 <br /> 1 1 <br /> '• s <br /> •� � ' 3 - _ , <br /> 1 Establish a line from point A to point B by <br /> temporarily marlcing each point with a nail. <br /> The line must be parallel to the eave and in <br /> this example 3'long(this is the 3 side ofthe <br /> 3._4...S...Triangle). NOte: <br /> a for larger 3._4._S...Triangies muttiple <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 fador of 6 for an <br /> 18:_24:.30:..Triangle. Obviously, the <br /> �• , � � , doser the triangle vertical leg length is <br /> to matching the panel length, the <br /> greater the squaring accuracy. <br /> . <br /> �7 <br /> � 3 <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 wiil be the square reference line for <br /> �� the MasterRib�panei insta�lation. <br /> �.�_____,_ - — �--°-°-- �"} <br />
