AZEK’s grooved decking boards work best when complemented by AZEK CONCEALoc or AZEK FUSIONLoc Hidden Fasteners. When working with square-edged boards from AZEK, installation crews prefer hidden fastener systems such as Pro Plug and Cortex®. Plugs are made from the same decking board, therefore they are almost invisible. By using FUSIONLoc or CONCEALoc and Screws with Plugs – you can have a complete fastener-free surface. Other fastener systems can also fit well with AZEK decking boards but be sure to confirm compatibility with AZEK and your fastener manufacturer before trying them.
