This purlin upgrade set adds structural support to the left and right sides of your ridge pole, preventing your hoop house from twisting or collapsing in high winds. It's recommended for tunnels at least 20' wide in windy areas and required for those over 20'. Sold in increments of 20 feet, this set includes all necessary connectors and hardware. Priced at just $97.26 (compare at $359.99), you save 73%—a smart investment for your greenhouse's longevity.
Purlins run parallel to the ridge pole and tie the hoops together, adding lateral stability. Without them, high winds can cause the structure to rack and fail. If you're building a high tunnel or hoop house, this upgrade is essential for durability.
Ideal for retrofitting existing hoop houses to improve wind resistance, or as an add-on to new builds. Perfect for commercial growers in open, windy locations.
At $97.26, this set is a fraction of the $359.99 original price—saving you $262.73. Use code GARDEN15 for an extra 15% off, and enjoy free shipping if your order totals over $45.

Each set covers the left and right runs parallel to the ridge pole. For a 20-foot hoop house, one set (20 ft) is typically sufficient, but check the length of your hoop house to confirm.
The set includes ridge poles, hoop cross connectors, endwall cross connectors, and bolts & nuts. Everything you need for installation.
I added this to my 30' hoophouse to strengthen it against wind gusts. Installation was straightforward, and it made a huge difference. The price is unbeatable compared to other options.
This set added the extra support I needed. It took a bit of time to install, but it's worth it. The sections are sturdy and well-made. My hoophouse no longer shakes in strong winds.
The purlins do their job, but I expected the set to include more hardware. It only came with the tubes, so I had to buy extra clamps. However, the quality is solid.
