Abstract: An outdoor lattice system comprises at least two posts and a plurality of modular lattice systems configured to be disposed between and supported by the at least two posts. The posts have an elongate body comprising multiple support openings arranged along the elongate body. Each of the modular lattice sections comprise a body, a first edge and a second edge, each edge being a longitudinal edge of the body, the second edge opposite to the first edge, each of the first edge and the second edge comprising a support element extending outwardly therefrom. The support element is configured to couple mechanically with a support opening from the plurality of support openings of the first post, and the at least one support element on the second edge of the first modular lattice section configured to couple mechanically with a support opening from the plurality of support openings of the second post.
