Whether you're a backyard grower extending tomato season or a small-farm operator covering a 30 ft. hoop house, this 30-pack of greenhouse wiggle wire and aluminum lock channel is built to hold your poly film and shade cloth through wind, rain, and freeze-thaw cycles. Each kit pairs 30 aluminum alloy U-channels with 30 PE-coated spring wires, factory-matched so the wire seats fully into the channel without gaps that let wind ripple and tear the film. The smooth PE coating keeps sharp wire edges off the plastic, dramatically reducing the small tears that grow into season-ending rips, while the aluminum channel resists rust and corrosion through humid grow cycles. Each 6.56 ft. (2 m) channel bends easily over flat, gothic, and arched hoop frames, and the 0.05 in. thickened profile holds shape under load. The system is fully reusable — pull the wire, swap shade cloth for winter poly, and reinstall the same hardware year after year. Included fasteners let you mount the channel to wood or steel framing, lay the film, and press the wire home to lock everything in place. Each channel measures 79.1 x 1.2 x 0.4 in. — confirm your hoop spacing matches before ordering.
