This durable anchor rod is specifically designed for heavy-duty applications in solid rock, featuring a robust construction of malleable castings and a triple eye design. Hot-dip galvanized to meet stringent ASTM Specification A153, it resists corrosion while ensuring long-lasting performance. To install, a drill creates a 12-inch deep hole where the anchor is placed; as the rod is turned, the anchor expands to tightly wedge itself in place, achieving an impressive ultimate strength of 36,000 lbs. With an anchor diameter of 2-¼ inches and an expanded size of 3-⅛ inches, this piece provides reliable anchoring for various aerial hardware and poles, making it an essential tool for construction and rigging professionals.
