THE DUCKBILL PRINCIPLE
Ancor Loc’s DUCKBILL anchors, a labour and time saving device, it works like a toggle bolt in soil. DUCKBILLS are driven into the ground, 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. Download the Duckbill Brochure.
