Duckbill Earth Anchors

Duckbill Earth Anchors

earthanchorSafer than conventional anchors, Duckbill earth anchors leave no rigid rods, stakes, pipes, or stems above ground to injure people or damage equipment. Made of high-impact and shock-resistant Tenaloy aluminum alloy, Duckbills will not rust or corrode. High-strength galvanized aircraft cable has wedged loop end for easy tie-off. These anchors are ideal for anchoring bird pens, small buildings, and equipment. Here's a forward view of a Duckbill Earth Anchor:

Duckbill Earth Anchor

Duckbill earth anchors are easy to install, saving labor and time. Anchors are driven into the ground using a hand tool, drive rod or small power equipment with minimum soil disturbance. No digging is required. Wherever you can drive or drill into the ground, you can use a Duckbill.

Once driven to the desired depth, an upward pull on the cable rotates the Duckbill into a load-lock position. Further upward tension causes the anchor to plane sideways through the earth against undisturbed soil, resisting pullout and increasing holding power.

The heads are available in both ductile iron and aluminum castings.

  • Anchors are available with either galvanized or stainless steel pre-attached aircraft cable.
  • Standard lead times are roughly ten working days + transit
