Our Vinyl lattice is the perfect thing to top off a perfect vinyl pergola. It provides some shade protection, and also is a good frame for your clinging vines. This installs easily with a few screws to the top of your top runners. We use the heavy duty 3/16" thick lattice, which is surprisingly durable and tough.
