The UltraShield Locking Clips (TC-1) are part of the official hidden fixing system for grooved edge UltraShield composite decking boards. These stainless steel clips are designed to lock each decking board firmly into place, creating a secure, long-lasting deck structure with no visible screws.

Used in combination with the CEC (TC-2) expansion clips, TC-1 clips ensure the board stays anchored at key points while still allowing natural expansion and contraction across the rest of the deck.


🔹 Key Features:

Secure locking clip for grooved edge UltraShield boards
✅ Ensures a strong mechanical hold with hidden fixing
✅ Made from high-quality stainless steel – corrosion resistant
✅ Works alongside TC-2 CEC expansion clips for proper board spacing
✅ Provides a clean, screw-free finish on the deck surface
✅ Suitable for residential and commercial decking projects


🔹 Usage Guide:

  • Place TC-1 locking clips on the first joist of every board to prevent movement

  • Use TC-2 expansion clips on the remaining joists

  • Recommended layout: 1 x TC-1 clip per board, the rest TC-2 for balanced flexibility and strength


The TC-1 clip is a critical component of the UltraShield hidden fastener system, ensuring that your deck stays stable, safe, and sleek — with no compromise on appearance.
