treated post.
NOTES:
» TREX TRANSCEND RAILINGS ARE DESIGNED TO BE INSTALLED OVER THE DECKING FRAME OR ON INSIDE OF RIM JOIST. NOTCHING OF 
PRESSURE-TREATED POSTS OR POSTS INSTALLED ON OUTSIDE OF RIM JOIST IS NOT ALLOWED.
» All Trex Transcend railing lengths are manufactured at ON CENTER dimensions (spanning from center of each post): 67-5/8" (1718 mm) for 
6' (1.83 m) on center, and 91-5/8" (2353 mm) for 8' (2.44 m) on center. Note that railings are designed to be slightly longer than required to 
allow for very slight play in post placement – some minimal trimming may be required. IT IS VERY IMPORTANT TO MEASURE FIRST.
» Ensure that pressure treated posts are installed at proper height so that when post sleeves are installed, both pressure treated post and post  
  sleeve are flush at top.
