HOW TO INSTALL COCKTAIL STYLE GLASS PANEL RAILING 
TREX TRANSCEND
NOTES: Read all instructions BEFORE installation. 
»   You must purchase the 1/4" (6 mm) tempered glass 
panels. See dimensions below.
»   Glass panels ONLY for use with maximum 6' (1.83 m) 
on center post spacing.
»   NOT recommended for stair applications.
»   Trex post mounts cannot be used for this application.
»  If using Select decking, USE maximum length 1-3/4"
(45 mm) screw and NOT 2" (51 mm) screw.
»  Screws that are used for attachment of decking 
board to railing MUST be attached at angle to 
prevent screw from penetrating through top of 
decking board.
»  DO NOT use Enhance (scalloped profile) or Escapes 
deck boards for top rail over universal rails.

Attaching Top Rail
9. Cut deck boards to appropriate length of railing 
span, remembering to include extra space on each 
side of the deck board to allow for attachment to the 
post. Decking boards must cover 1/2 of the pressure-
treated post to allow this to be fastened later. If you 
include extra decking material on each side, this can 
be cut off later if needed.
10.  Place inverted deck board (top side of deck board 
down) on clean, flat surface. 
11.  Place Universal rail (orient this properly so when 
flipped over, the universal rail will accept the baluster 
spacer and balusters), on the deck board, centered 
in both directions to allow final attachment to post.
