Only Fiberon Phantom hidden deck fasteners are recommended for use when installing Fiberon decking. (Note: hidden fasteners will only work with grooved edge boards, not square end boards.) Using another manufacturer’s product will void your warranty, and may result in an unsatisfactory installation. Trex Universal Clips, for example, do not hold the boards securely during thermal expansion and contraction caused by temperature swings. Consequently, you could experience significant end-gapping issues.
Always read and follow Fiberon decking installation instructions to ensure correct installation and keep your warranty coverage intact.
