Anchor - Arrowhead

Use these anchors to secure TallTowers in rocky soil.

  • Anchor - Arrowhead

Configuration Options

Use arrowhead anchors when rocks in the soil will prevent the successful installation of screw-in anchors.

The arrowhead anchor’s unique triangular design allows it to thread its way between rocks in the soil. The anchor is driven into the ground with a hardened steel drive rod. Once in the ground, the drive rod is removed, and upward force on the attached cable rotates the anchor perpendicular to the cable for maximum holding power.

Cables are made of galvanized 7 x 19 steel, and the arrowhead is iron.

  • Trusted performance in rocky soil types – up to 1905 kg (4200 lbs.) holding power in certain soil types
  • Simple installation using a drive rod
