The Berkeley Heights Arbor is environmentally friendly and is made of Poly Wood. The majority of the material is made from recycled plastic. The color will not fade and a UV inhibitor is added to the vinyl to protect it from the sun's ultraviolet rays. They keep their great appearance for many years and only need a periodic cleanup that can be done with soapy water and a soft bristled brush. This Arbor has an opening width of 48" with a depth of 35". It is available in Square Lattice only.
