HOW TO INSTALL ON-AN-ANGLE RAILING 
TREX ENHANCE
®
NOTE: Brackets are designed to be installed up to a 45° angle.
»   Both 4" x 4" or 6" x 6"
post sleeves work well for angles 
u
p to 45 degrees. Bottom rail 
brackets may need to be slightly 
offset to one side in order to fit 
properly to hold rail in place. 
Measure and mark first before 
attachment of bracket to rail 
to ensure bottom rail remains 
parallel to upper rail.
4. Attaching Foot Block to Bottom Railing
See instructions on page 2.
Notes: 
»  If installing in weather below 40°F, leave 1/8" gap between
deck boards.
»  Deck boards can overhang end of last post maximum 1/2" .
Cutting Deck Board
5.  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.
6.  Place inverted deck board
(place top side of deck
board down) on clean,
flat surface. (DO NOT use
Enhance or Escapes deck
boards for top rail.)
Attaching Deck Board to 
Enhance Top Rail
7.
 Place inverted Enhance
top rail (orient properly so
baluster holes are shown
top side up), on the deck
board, centered in both
directions to allow final attachment to post.
8.  Secure deck board 
to Select top rail with
#8-3/4" truss-head
self-drilling screws (not
provided) approx. every
16" on center. Screws are
to be installed inside of
the baluster holes into the
decking board. DO NOT overtighten.
NOTE: 
A long drill bit will be required to fit inside the
baluster holes.
