An exhaust hood from mechanical drawings is supported by typical L102x102 structural angle hangers suspended from the underside of truss bottom chords. A C150 channel spans between members, coordinating with structural depth confirmed as 620 millimeters with mechanical drawings. Single diagonal angle braces of size L76x76x6.4 and horizontal angles of size L76x76x6.4 frame into the hangers. An additional diagonal member of size L64x64x4.8 provides a force resistance of Cf equals twenty kilonewtons, applied typically on two sides.
