Wallbarn W Clip – Class A Hidden Fixing Clip for Fire Deck & Exadeck Decking (Pack of 100 + Red Jig)
The Wallbarn W Clip is a next‑generation hidden fixing solution engineered specifically for Fire Deck Fibre Cement Decking and Exadeck Porcelain Decking. Manufactured from electrocoated aluminium and boasting a Class A Fire Class Rating, this innovative clip is purpose‑built for non‑combustible decking systems where safety, precision and durability are essential.
Designed to work with Deckboards featuring a central side milling profile, the W Clip delivers a clean, concealed fixing that enhances both the performance and aesthetics of your decking installation. Available in 30mm or 60mm lengths, each clip ensures a consistent 5–6mm gap between boards thanks to its 5mm underside width.
Installation is streamlined with the included black stainless steel screws, which come pre‑inserted into the clip to prevent loss and speed up fitting. Every pack also includes a red drilling jig to ensure accurate pilot holes—an essential step for correct installation.
Developed exclusively by Wallbarn, this bespoke clip integrates seamlessly with the Fire Deck CDeck and Exadeck substructure systems, offering a secure, reliable and fully compliant fixing method for A1 fire‑rated decking projects.
