Over time, as the timbers expand and contract with changing seasons, these dynamic joints maintain a close-fitting connection, minimize gap exposure and reduce typical twisting and warping.Save time and headache during installation, get superior strength and quality, and extend the life and beauty of your investment with the remarkable Dovetail System!
