When using any of the engineered components mentioned above do not cut, notch or bore holes in any element without checking with the designer or manufacturer. To indicate the limitations of such boring, please see Fig. 4.5 reproduced from Trus Joist's technical manual. It should be noted that this applies to this particular manufacturer's product, but similar information is available from all of the manufactured joist and beam companies. It should be carefully noted that no notching of top or bottom flange, i.e. the most highly stressed areas, is allowed.
