Post Sleeve Installation
BEFORE YOU INSTALL POST SLEEVES
Rail posts may be installed by using the structural posts that support the joists, additional pressure-treated 4x4 (101.6 mm x
101.6 mm) lumber, or by using a surface mount bracket. The Fiberon Surface Mount Bracket requires that the thickness of the
decking and reinforcement boards underneath the deck be a minimum of 5 in. (127.0 mm). This equates to two structurally sound
2 in. x 8 in. (50.8 mm x 203.2 mm) treated lumber boards and one structurally sound 1 in. x 8 in. (25.4 mm x 203.2 mm) treated
lumber board under the 1 in. (25.4 mm) deck board, unless otherwise specied by local building codes. To optimize post placement,
additional joists, blocking, or alternative locations may be required. Determine post placement and install reinforcement boards prior
to installing the deck surface. Use a scaled drawing of your project or the online Fiberon Deck Design Tool to determine where posts
will be installed. For proper aesthetics, divide the perimeter dimensions evenly so that posts are spaced equally. Composite guardrail
systems should be secured only to code-compliant posts.

INSTALLING POST SLEEVES TO STRUCTURAL POSTS
Guardrails can be secured to structural 4 in. x 4 in. (101.6 mm x 101.6 mm) posts, or to 4 in. x 4 in. (101.6 mm x 101.6 mm) posts secured
to the support framing in a code-approved manner. Always check to ensure posts are plumb and true. Check maximum and minimum
distance requirements for the railing that is being installed to ensure a snug t and proper baluster spacing.
