Note: This listing is for the wire only, not the wirelock channel itself.
You are purchasing 6-foot sections of wire only.
Wire Lock is used for fastening poly film and/or shade cloth to your greenhouse. This is a great, easy way to attach plastic that lasts for years.
Made out of galvanized steel, the wire fits into the base, which is attached to the first and last bows with self-tapping screws, as well as along the greenhouse base. This can hold both the film and shade cloth in place.
