Fortress 7lb. anchor. Precision-machined from an aluminum alloy that is as strong as steel, but only half the weight. Rustproof. Sharper than heavy, dull-edged steel anchors. Will set faster and penetrate deeper into common sea bottoms for incredible holding power. Excellent as a spare or storm anchor. Easy to store. Adjustable 32 deg. to 45 deg. fluke angle which is an exclusive and patented feature which dramatically increases holding power in problem soft mud bottoms. Tough anodized finish with a handsome and durable appearance. Corrosion resistant
