Landscape Fabric Pins are a great way to properly secure and anchor landscape fabrics, ground coverings, drip irrigation tubing, or tack down deer fencing. These 11 gauge galvanized steel pins are angled at the ends for faster and easier installation. Use 4" pins in rocky soils - 6" pins in normal soils. Consider a Pin Setter Tool if you have a large area to cover, this well made tool will save you time and pain!!!
