Wood Framing

For wood framing, and if using Trex Universal Hidden Fasteners, pre-drill and toenail an approved screw at an angle in groove at both ends 25mm from board end and center of each board. For metal framing, use two approved decking screws at board ends.

Routing Square Edge Boards for Trex Hideaway Hidden Fasteners NOTE: All Trex square edge profiles can be routed.

Using a Trex router bit with standard router: 1. Rout from bottom side of board. 2. Rout the entire length of the board, or at every intersection where board is over support joists.

NOTE: Construction methods are always improving. Please refer to www.trex.com for the most up-to-date installation requirements.
