Our trellises are constructed from High-Density-Polyethylene (HDPE) mesh that's designed to withstand all weather conditions. The mesh provides excellent rust resistance and maintains its appearance for years.

Will this work with my downspout size?

Our trellises are designed to fit most standard residential downspouts, including 2x3 inch and 3x4 inch rectangular downspouts, as well as 3-inch and 4-inch round downspouts. If you're unsure about compatibility, please contact us with your downspout measurements.

Each trellis can safely support up to 47 pounds of plant material when properly installed. This is sufficient for most climbing plants, vegetables, and flowering vines.
