Abstract: A prefabricated load-bearing header. An outer frame in the form a rectangle has four 2 by 4 boards joined together at their meetings ends at 45 degree angles. Within the inner perimeter of the outer frame are two sets of grooves extending lengthwise of each frame member. Two webbing supports extends across the opened formed inner perimeter of the frame and are joined to the inner interior of the frame near its mid point at one end and the corners at the other ends. These webbing supports provide increased strength to the frame structure. Covering the webbing supports are two sheets of chip board material cut to fit within the two sets of formed framing member grooves along the edges of the sheets. The grooves have a width approximately the same as the thickness of the sheets of chip boards which fit into them. The length of the framing members can be made to any desired length.
