I only needed 8 feet in length. The nylon trellis is strong and does not get hot and burn those tender plants in this Texas sun. I picked up two while I was at it, in case I want to add another trellis later.
I purchased four 2 x 3 x 8 untreated lumber from Lowes. One for each end and one in the middle for additional support. The fourth board will be installed at the top to connect them and support the structure. I purchased a few inner brackets to make it easy to attached it.
