Techniques are provided for determining relevant information from a document based on document structure. The legs of the cap member upon which the clips are installed are very stiff by virtue of being reinforced by gussets that resist deflection of the legs when inserted in a picket. The cylindrical body includes an internal bore, the first end includes a receiving bore and the second end includes a discharge bore aligning with one another. The invention also includes roll forming apparatus adapted for producing metal framing of this type, and particularly adapted to produce metal frame members having a predominantly C-section profile, with one or more portions of a U-section profile, the U-section and C-section profiles formed simultaneously on the same sheet metal strip.
