When  2-inch  (50.8  mm)  square  screen  post  at 
96 inches long is installed with 42-inch Aluminum Railing 
System, the posts with L-brackets must be fastened to the

When  fascia  bracket  assembly  is  used  in  lieu  of  post 
base for 3-inch (76.2 mm) square posts installed over the 
supporting  concrete  substrate  having  a  minimum 
compressive strength of 3900 psi (26.9 MPa), the posts 
with  fascia  bracket  assembly  must  be  fastened  to  the 
supporting concrete substrate using four ¼-inch x 3-inch 
long  (6.35  mm  by  76.2  mm)  corrosion  resistant  coated
