RAILING— 
a lot easier than it looks
Selecting the right railing is pretty easy, but 
each Trex railing line is a little different. Please 
read the system descriptions at the top of each 
product section so you can choose exactly which 
railing components you need to complete your 
design. For additional guidance, the chart to the 
left depicts each railing system's components.
Each 4x4 and 6x6 post sleeve fits over a 4x4  
pressure treated post or equivalent post mount.
Also available with LED lighting. See page 12.
