IMPORTANT NOTES:
PRIOR TO INSTALLING DECK BOARDS:
It is very important to have the
Universal Rail (positioned
on top) even with the top of the post sleeves
to keep from
seeing gaps under the Drink Rail.
The tops of all
4x4" posts must be within ¼" of the tops of
post covers
for proper fastening of deck boards.
It is recommended to drill a
slight countersink
into the
surface of the support rail so that the head of the screw
sits just flush to slightly above the surface. Do not over
countersink. Without countersinking, the Universal Rail
may not sit flat against the support rail.
IMPORTANT NOTES:
• Pre-drilling with a 3/16" drill bit is always required when
installing Cortex or applicable TOPLOC in TimberTech
PRO and EDGE decking.
• The Cortex Setting Tool must be used to set the Cortex
screw to the proper depth.
• 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.
• The interaction between the deck board, screw, and plug
is essential.
For
Over-the-Post Applications
, fasten deck board to posts
with (3) 2 ½" SS Cortex or applicable TOPLOC screws (not
included) on either side of a butt joint. For butt joints, install
(3) screws on either side of butt joint into post.
Fasten no
closer than 3/4" from the outside edge and ends of each
plank
(Dia. #3A, 3B)
. 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
(Dia. #3B)
.
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
TimberTech Classic Composite Series Railing Install Guide
for details.
