DECKMASTER® is a patented fastening system that eliminates the damage to deck boards caused by other fastening systems. Screwing or nailing through the top of the deck boards is not only unsightly, but also allows the wood to crack, warp, split, rot, stain, pop up and become a possible hazard to bare feet. The fastening system enhances not only the look of the deck, but last years longer than conventional decks.
