Which diameter is outside the specified anchor rod range?

Which diameter is outside the specified anchor rod range?

• A. 1/2"
• B. 1"
• C. 1 1/4"
• D. 2"

Answer: (D)

Anchor rods come in a defined set of diameters that fit the hardware, the base-plate holes, and the embedment specified for the system. Each size is chosen to ensure proper nut seating, clearance, and reliable load transfer. The smaller diameters listed—like 1/2 inch, 1 inch, and 1 1/4 inch—are all within the typical range that standard anchor assemblies are designed to accommodate. A diameter of 2 inches, however, is larger than what the specified system supports; it wouldn’t fit through the base-plate holes, would require a different anchor design and larger installation details, and could invalidate the load-path assumptions. So 2 inches is outside the specified anchor rod range.
