Featured Hardware: Trex Secret Fixings

Trex Hideaway® Secret Fixing System

In pursuit of the perfect deck, all Trex® decking lines come with a hidden installation option. When using grooved-edge boards, our secret fixing system installs between the deck boards, fastening them to the joists with no visible screw heads on the walking surface. This precision also creates perfectly consistent spacing between the boards for a flawless look across the entire deck. This system includes a few simple components:

Groove Cutter

Traditional square edge boards require traditional deck screws for installation; however, using a Trex groove cutter routes the necessary underside groove into any traditional board to accommodate our hidden fastening system.
