SIGNATURE RAILING
IMPORTANT NOTES:
» EACH POST MUST BE ATTACHED AS SHOWN TO ENSURE A CODE-
COMPLIANT AND SAFE INSTALLATION.
» SIGNATURE POSTS CANNOT BE USED WITH SIGNATURE TRADITIONAL
OR SIGNATURE COCKTAIL DESIGNS, ONLY Pressure-treated POST/POST
SLEEVES CAN BE USED. REFER TO DETAILED INSTRUCTIONS FOR MORE
INFORMATION.
» ALWAYS refer to your local building code official prior to installing
any railing system to ensure all code and safety requirements are met.
Trex® cannot be held responsible for improper or non-recommended
installations.
» When installing Signature posts on ACQ, CCA or concrete surfaces, use
an appropriate isolation barrier between post and surface (contact local
building code official if needed).
» For installing Signature Post and/or Signature Crossover Posts, see below.
» For pressure-treated posts, post sleeves, and skirts, see detailed
instructions provided with Signature Railing Kits.
» All Signature stair installations require the use of a 53" (1346 mm) stair
post, measured and cut to appropriate length if necessary.
» If crossover stair post is required, use stair post (again cut to
appropriate length if necessary) and use swivel crossover bracket.
» If installing on concrete, make sure all surfaces are level.
