Added Strength: Modified T-shaped cross-section puts more metal where strength and bending resistance are needed most * Lightweight: Extruded from aircraft-grade, heat-treated aluminum for optimum strength-to-weight performance * Better Resistance: 20% increase in holding power over other pickets * Faster for Safety: Multiple attachment points at 3-inch/7.6cm intervals along the neutral axis ensure a quick and strong anchor at variable depths * Works in sand and silt in addition to snow
