These are a durable & decorative panel. 1800mm x 1200mm Available treated in Green only. They have 'herringbone' joints, and are screwed for durability. The Lattice is spaced at 50mm. All panels are 1800mm wide, the heights are measured from the bottom-center, to the heighest point center. A nice Panel but not as strong as a close board fence panel. You may need fence packers if you are going in to existing fence posts.
