INSTALLING TREX SIGNATURE POSTS AND/OR TREX SIGNATURE CROSSOVER POSTS ON WOOD
IMPORTANT NOTES: » EACH POST MUST BE ATTACHED AS SHOWN TO ENSURE A CODE COMPLIANT AND SAFE INSTALLATION. » TREX SIGNATURE POSTS CANNOT BE USED WITH TRADITIONAL OR 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 Trex Signature posts on ACQ, CCA or concrete surfaces, use an appropriate isolation barrier between post and surface (contact local building code official if needed). » All Trex 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. » In areas of extreme cold/cold weather conditions (ex. ice/snow) its recommended to drill a small weephole at the base of the post (can be hidden under post skirt) to allow for water drainage.
