We recommend using these only on permanent installations. Cementing the corners and every other post in the ground is the best way to ensure a rock-solid tunnel.
Our Ground Post upgrade kit adds 1-2 feet of height to your Caterpillar Tunnel (depending on how deep you put them in the ground), allowing for easier access to the beds along the edges. The extra height also comes in handy when trellising crops such as Tomatoes or Cucumbers.
Each Ground Post is 48” tall with one swaged end. Purchasing 22 posts will be enough for a 50’ tunnel, 42 posts for a 100’ tunnel. Each post also includes one band clamp and carabiner.
