There are <br /> four logs across the top of the window. Two of the logs are <br /> continuous, the other two are spliced over the window opening. <br /> The opening is 9' -6" (+/-) . <br /> The header as is, is not capable of supporting the roof truss <br /> and snow load required by code. <br /> I recommend that (8) eight 5/8" diameter bolts be equally <br /> spaced horizontally across the window opening. These bolts <br /> shall be installed vertically through the four logs above the <br /> window. <br /> It is my opinion that these bolts will make these logs act as <br /> a composite section. This will support the necessary loads. <br /> Feel free to call me if you have any questions. <br /> Siri�rely, <br /> j ,/ n <br /> �:-_ .�-'�,�,,� �����`..�. ��' <br /> Kesh P.
