Post Installation: » If Trex Signature Stair posts are used, install at nose of stair tread directly under required blocking. See Trex Signature horizontal post instructions for details. » If installing pressure-treated posts, please refer to local building code requirements prior to attaching pressure treaded posts. Pressure treated posts must be installed on the inside of the stair stringer and at the nose of the stair tread. In most cases, a pressure-treated post and post sleeve longer than 39" will be needed for stair applications.
