The Lancaster Trellis made by Dura-Trel has a classic grid design. It's a great way to dress up your outdoor space. This trellis has a solid frame and the square lattice pattern allows tendrils and leaves climb up with ease. It never needs to be sanded, painted, or stained. When the trellis is dirty, simply spray it down with a garden hose. This trellis is designed to be attached to a wall or fence.
