Jiggly Greenhouse® Cross-Connectors, commonly referred to as purlin brackets, allow secure connections to be made at the point where the hoop and purlin make contact. Made of high-quality galvanized steel, our cross-connectors tightly latch your ridge poles or purlins to your bow, to create an exceptionally sturdy greenhouse or hoop house frame. Cross-connectors are particularly useful in overhead greenhouse rail applications. As opposed to drilling and bolting, cross-connectors are a non-invasive way to construct your greenhouse structure quickly and easily. Jiggly Greenhouse® Cross-Connectors are available in an assortment of sizes to ensure the perfect fit and optimize the stability of your greenhouse.
