DUCKBILL® anchors, a patented labor and time saving device, work like a toggle bolt in soil. DUCKBILLS are driven into the ground (with no holes, no digging and no concrete), providing a safe and environmentally sensitive installation. An upward pull on the anchor tendon rotates the DUCKBILL into a perpendicular “anchor lock” position in undisturbed soil. The result: superb holding capacities. DUCKBILL anchor systems offer the most effective, lightweight and economical solutions to any anchoring application, large or small.
