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