2.  Where  the  opening  is  used  for  the  removal  of  noncombustible  material,  wire  mesh  may  be  utilized  in  lieu  of planking, provided such mesh is not less than number 18 gage wire mesh, with openings in the wire no longer than  ½  inch (13  mm),  and  also provided  that  the  wire  mesh  is securely  attached, in  accordance  with drawings developed by  a  registered design professional, to the shaftway  so that the wire mesh enclosure in  any  location does not deflect more than 2 inches (51 mm) when a force of at least 200 pounds (890 n) is applied along any horizontal portion of such wire mesh enclosure[.]; or
