The anchor boasts an impressive ultimate strength of 23,000 lbs, making it suitable for demanding applications where secure stabilization is paramount. Installation is straightforward; simply drill a 12-inch deep hole, insert the anchor, and turn the rod to expand it, creating a secure grip as the pull on the rod increases, thereby improving stability. With a 1-3/4" anchor diameter that expands to 2-3/8" and a hole diameter of 1-7/8", this anchor is a trusted choice for professionals seeking robust performance in aerial hardware and poles applications.
