The Cortex hidden fastening system is the fastest, easiest way to hide fasteners in composite, capstock and PVC decking boards. Cortex offers a strong connection between the deck board and joist. It hides fasteners across the entire deck, first and last board, perimeter and stairs. And it just got better.
