Expanding Anchor

Expanding or Bust Anchors are made for installation in augured holes. The bust anchor is formed by expanding wings that flare out.


Expanding (Bust) Anchors are made for installation in holes augured. One piece formed anchor with wings and a base. A retainer on the bottom holds the nut from the forged eye rod (sold separately).

During installation, a hole to the size listed on the table for the anchor is augured in line with the guy angle and to a depth based on the rod length. The rod is secured to the anchor and lowered into the hole. An expanding-and-tamping tool is used to strike the top of the anchor and open the blades into undisturbed soil. The hole is then back filled and tamped.

These anchors are coated with a rust inhibitor.
