Pyramid Mooring Anchor, 70lb. OVERWEIGHT! This item exceeds standard freight limits. Additional shipping charges may be applied to your order at time of shipment. The DorMor pyramid mooring anchor rapidly penetrates the bottom due to the highpoint loading of its compact size and shape. Once covered, the large surface area of the pyramid has a high suction effect. These anchors have been used successfully on the rough Maine coast since 1973. These made in the USA anchors are great for shallow water, and have been hurricane proven.
