Our Spring Wire upgrade kit helps turn your Caterpillar Tunnel into a more per­ma­nent green­house solu­tion. Spring Wire allows you to have tighter plas­tic, or help hold down shade cloth on your Caterpillar tunnel. 

In most cas­es, we rec­om­mend pair­ing Spring Wire with our Wind Bracing upgrade kit, allow­ing for increased wind pro­tec­tion, plus elim­i­nat­ing the need for the cone-shaped plas­tic bunch­ing at each end of your tun­nel. This is espe­cial­ly help­ful on urban farms or oth­er sit­u­a­tions where space is limited. 

The Spring Wire upgrade con­tains 93 inch­es of base chan­nel and 93 inch­es of 14 gauge Spring Wire. For typ­i­cal instal­la­tions we rec­om­mend 4 sets, allow­ing for two sets of Spring Wire and single chan­nel on each end bow. If you want the Spring Wire to extend all the way to the ground, you will need 6 sets for stan­dard tun­nels (3 for each end bow), and 8 sets for tun­nels with a lift (4 for each end bow).

Recommended quan­ti­ties for framed-in end walls are as follows:

  • 6 – 8 sets (3−4 for the top edge of each end bow)
  • 6 – 8 sets (for the door and framing)

For exam­ple, if you put an end wall with doors on both ends, you will need about 18 sets of Spring Wire and single chan­nel. Additionally, because wig­gle wire is expen­sive to ship by itself, we rec­om­mend pur­chas­ing them with a freight order, and padding the amount slightly.

We offer the 5‑pack, 10-pack, and 20-pack bun­dles to save on ship­ping costs.

Note: The way you frame in your end and the entry sys­tem you use will affect how many Spring Wire sets you need. Our rec­om­men­da­tions are gen­er­al in nature and ulti­mate­ly the amount need­ed will depend on your plans/context.

Farmers Friend works hard to a) get the materials right, b) get the customer experience right. I've seen few companies go to the lengths Farmers Friend does to ensure you get your product, know whats in it, and are able to put it to use in minimum time with minimum problems. Yes, you can buy pipe, bend it and go 100% DIY. But if you can't produce enough output in one of their tunnel kits to justify using their expertise in selection n grading materials and packaging it for you, maybe your entire cost/benefit equation needs reconsidered. Farming is hard work. Farmers Friend makes some of it easier.
