Guardian anchors benefit from years of Fortress research and development, and offer excellent quality, performance, and economy. These anchors are manufactured from the same corrosion resistant, high-tensile aluminum magnesium alloy as Fortress, which makes them stronger and lighter than competitive steel anchors. With Guardian anchors, several Fortress machining steps and extra features, such as anodizing and adjustable fluke angles, are eliminated. The result is a high performance anchor that is engineered for fast setting and strong holding power, and a very affordable alernative to those heavy, rust-prone steel anchors.
