INSTALLING DRINK RAIL – LEVEL PANELS
FOR IMPRESSION RAIL EXPRESS
®
3
IMPORTANT NOTES:
PRIOR TO INSTALLING DECK BOARDS:
It is very important to have the
Bottom Rail Cover
(inverted) even with the top of the posts to keep from
seeing gaps under the Drink Rail.
The tops of all
posts must be within ¼" of the tops of rail
covers for proper fastening of deck boards.
IMPORTANT NOTES:
• Pre-drilling with a 3/16" drill bit is always required when
installing Cortex or applicable TOPLOC in TimberTech
PRO and EDGE full profile/solid profile decking.
• AZEK
®
Cortex
®
requires the included TORX
®
ttap
®
drive
in order to set the screw to the correct depth for plugs.
• The Cortex fastener must be driven perpendicular to
the deck surface for proper fit and ideal finished look.
• The cored hole must be free of debris or moisture. Use a
smooth hammer head to set the Cortex plug.
For
Over-the-Post Applications, cut wood inserts from
4x4” wood boards to fit inside posts. Partially drive a wood
screw into wood insert to hold it in place during post bracket
attachment (remove afterwards). While holding wood insert,
install screws (from Panel Attach Kit) through bracket and
post into wood insert.

For
Over-the-Post Applications, fasten deck board to
wood post inserts with (3) 2 1/2" length AZEK
®
Cortex
®
or TOPLoc screws on either side of the butt joint.
Fasten
no closer than 3/4" from the outside edge and ends of
each plank
(Dia. #3B, 3C)
. Make sure that boards are tight
together at butt joints and no gap is left.
For proper screw
placement, measure 1 ¼" from center of board to ensure
ensure full contact with wood post insert
(Dia. #3C)
.
TIP: Pre-drilling significantly reduces spinouts in end grain.
Pre-drill through deck plank only, not into structural post.
It is also suggested to drill only half way through the plank.
Pre-drilling requirements vary distinctly by collection. See the
Deck Install Guide for details.
