LIEBIG® Anchor AS A4



Application of the installation torque causes the anchor’s two opposing cones to be drawn into the expansion sleeve. This causes the sleeve to be pressed against the sidewalls of the hole over its entire length and results in optimum frictional resistance and high load capacity in cracked and non-cracked concrete.
