This will ONLY work with our 14-ft wide tunnels and NOT the 16-ft wide tunnels.
Our 14-ft wide tunnel bows are made with 17-gauge (AWG) steel pipes and our 16-ft wide tunnels are made with 14-gauge (AWG) steel pipes.
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 12 – 18 inches 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. Each post also includes one band clamp and a carabiner.
