Made with the select northern white cedar, this trellis is naturally insect and rot resistant–lasting up to 20 years without using toxic chemicals. It features interlocking joints, a nifty easy-hang bracket and corrosion-resistant zinc screws (no staples) to ensure a solid trellis at a great value. A Nice Plus: Maine Trellis products are made by people with developmental and behavioral health disabilities, and this non-profit company is dedicated to helping these people achieve their goals in home, school, work and community.
