Take the (|ueition of rafters alone, m say a house 200 ft. long. In the narrow spacing 2') pairs of rafters are used. In the wide spacing, there are 17 or S less pairs. When you take rafters out of a greenhouse construction, it's a pretty serious matter. Tiiat strength must \>c put back some otiier way. To do it, we first use deeper rafters. Then we use heavier purlins, se- cured Id the rafters by an extra long fitting, extending the depth of the rafters and well out on the purlin The ridge is stiffened and held straight and true by a truss rod running between every pair of rafters. Eunning from it i)erpendicular to the eave and through each pur- lin, is a sag rod. To overcome any possibility of eave sag, a secondary post is placed midway between the reg- ular posts. The cuinbined result of all of which 's, that the wide spaced house as we build it, is just as strong as the old spacing and the house is decidedly LIGHTER, .lust as strong and lighter. That's what you are looking for, isn't it? You know we go anywhere for business. Or to talk business. m Look carefully and you can see the secondary rafter and sai.' rod running from it through the purlins lo the eave and secondary post.
