Protect your crops with a durable Caterpillar Tunnel Kit designed to provide reliable crop protection without the added cost and complexity of a traditional high tunnel. Combining the simplicity of a caterpillar tunnel with the strength of a hoop house, this polytunnel is an efficient solution for extending growing seasons, shielding plants from harsh weather, and creating a protected growing environment.
The steel framing is 100% U.S.-made, with the components cut, bent, and fabricated at our Texas facility. While the frame is manufactured in the USA, some components, including greenhouse film and nuts and bolts, are sourced internationally.
Designed for growers who want the benefits of a polytunnel or hoop house without end walls, hip boards, or baseboards, the Caterpillar Tunnel offers a straightforward structure that is easier to assemble and operate than many traditional high tunnels. Its robust steel frame provides greater durability than standard caterpillar tunnels while maintaining the open, practical design growers need.
Choose the Caterpillar Tunnel Kit with Butterfly Doors for a dependable and cost-effective way to protect crops, improve growing conditions, and keep your farm productive throughout the season.
PRODUCT FEATURES
- Triple-Layer Protection Tubing: Combines zinc, conversion coating, and a clear organic polymer for a durable, strong, and visually appealing finish.
- Ridge Pole and Wind Braces: Made from 1.375” OD 16 GA Texas-fabricated, US-sourced steel tubing, these features add rigidity along the top spine of each hoop and prevent frame movement.
- Structural Integrity Upgrades: Traditional CAT tunnels are reimagined with 1” OD 16 GA ground posts, triple-layer protected, US-sourced steel tubing, replacing rebar pins for deeper ground anchorage and enhanced stability.
- Optional Truss Parts: Available for areas with high winds or heavy snow, these parts are made from the same high-quality material for additional lateral support.
- Ventilation and Plastic Securing Mechanisms: Includes a Batton Strap for securing greenhouse plastic and hoop springs for manual side curtain ventilation, with an option to upgrade to roll-up sides.
- Innovative Butterfly Doors: These unique doors streamline end-wall management, providing easy access, efficient ventilation, and effective protection against weather elements. No more bunching up loose plastic at the ends; laborious and unkempt loose plastic is unsightly and a potential fail point. Rapidly open and close your entire end wall to vent or move equipment and harvests in and out of the tunnel. The clamshell design sheds water and winds over your tunnel during rain events and dumps heat build-up in the summer with easy closing and opening.
- Scalability for Growth: The design allows for future additions such as end walls, hip and baseboards, and other customizations to accommodate expanding farming needs.
