Rust-Resistant Aluminum Lock Channels - Crafted from lightweight aluminum alloy, these lock channels outperform traditional galvanized iron with better rust resistance and durability. Ideal for humid or coastal climates. PVC-Coated Spring Wire - The chemically stable PVC coating not only withstands humid and coastal climates, but also features a polished surface that safeguards poly films from abrasion damage during installation and use. Time-Saving Installation - Using self tapping screws to install lock channel, you don't need to pre-drill. Once the plastic or shade cloth is installed over the greenhouse, you just need to wiggle the wire into the lock channel to lock the covering material in place Bendable To Suit Different Greenhouse - You can bend channels into an arch for your need because of the bending ability of aluminum alloy. Secure Packaging - All components are sealed in multiple layers of heat-shrinkable film and then packed in corrugated boxes to prevent damage and loss of parts during transportation. 40-Pack Greenhouse Spring Wire & Lock Channel Kit
