Framing & StructuralQuestion 326 of 700
On the jobsite, cutting, notching, or drilling the chords or webs of a prefabricated wood truss is:
a.Allowed if done neatly with a sharp saw
b.Allowed for the top chord only
c.Allowed up to 25 percent of the member
d.Prohibited unless specifically permitted by the truss design or an engineer
Explanation
Truss members are engineered as a system, so no chord or web may be cut, notched, or drilled unless the truss design drawing or a registered design professional specifically allows it. Neat cutting, top-chord-only cutting, and a 25 percent rule do not apply to engineered trusses.
