The CHANCE® corrosion-protected disc anchor is designed for low resistivity, alkaline and acidic soils with electrolyte combinations. The anchor eye is forged directly to the rod, so the eye is an integral part of the anchor. The anchor's flanged cap nut is cast. It's large and heavy for greater protection. The heat-shrink sleeve over the galvanized anchor rod helps prevent moisture from going down the rod.These rods include fiber-reinforced washer and heavy-forged cap nut. The galvanized rod has asphalt coating, polyethylene tube and heat shrink collar.
