"This is a portable, 16', snowboarding rail made of wood with a PVC sliding surface. The entire wood frame is stained and varnished so it will withstand any moisture from the environment. I built this last winter and only got to use it once and it has been stored indoors. The rail breaks down into two 8' sections and a middle support piece. This allows for compact vertical storage as shown in the picture."
They even stained and varnished it, how thoughtful.
