5. NOTE: RIM JOIST
REMOVED TO SHOW
PROPER ATTACHMENT
OF HARDWARE.
Level posts if
necessary using
stainless steel leveling
shims (provided).
Ensure that post is
placed on decking
surface so that it clears
the rim joist and there
is enough clearance on
the underside blocking
for the back plate to be
installed.
Attach posts using four
3/8" x 6" (0.95 cm x
15.2 cm) stainless steel
hex cap bolts, washers,
and nuts, along with using metal back
plate on underside of blocking. Metal back plate
MUST be installed under the decking to ensure
this will meet code compliance. (Hardware for deck
surface mounting can be ordered as separate item
from Trex.)
