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.
