Lightweight aluminum sections resist corrosion and maintain a cooler water temperature while supporting and eliminating sagging lines. The simple U design makes it easy to install and versatile to use with upright, drop inversion, and overhead irrigation or horizontally with drip lines and supply lines. The rail extrusion also adds support to the Poly-Rail with a functional ridge for easy connections. Locking tabs are installed at the end of each run so that two or more hangers, along with a connecting strip every 12 feet, can be put on each section. This allows for hanging baskets to be supported at 4-foot intervals.
