DeckWise® Thermo Clip Hidden Decking Fixings – 6 mm Gap (175-Piece Kit)
The DeckWise® Thermo Clip system is a high-quality hidden fastening solution designed for thermally modified and side-grooved decking boards. It creates a clean, screw-free surface while maintaining a consistent 6 mm gap between boards for drainage and airflow.
This 175-piece kit is ideal for use with Thermory / ThermoDeck style boards and other compatible grooved profiles. Clips lock securely into the board groove and fasten to the joist, helping to reduce splitting at screw heads and extending the life of your deck.
The system is perfect for both residential and commercial decking where a neat finish and long-term performance are important. Hidden fixings also make future board replacement easier, as individual boards can be lifted without damaging the visible face.
Use this kit wherever you want a high-end, contemporary finish with fast installation and reliable long-term performance. For best results, always follow the DeckWise® installation guidance and check compatibility with your chosen decking board.
