The undercut fixing system that does not require a special setting tool.

The LIEBIG SUPERPLUS is available in zinc plated carbon steel and A4 stainless steel. Its design offers the high load capacity and reliability of an undercut anchor, but with the ease of installation of an expansion anchor.

In contrast to competing undercut anchor systems, the SUPERPLUS does not require special drill bits or setting tools. You need only apply the torque to create the self-undercut.

liebig superplus features


Automatic self-undercutting. The unique design of the SUPERPLUS causes an undercut to be created when the installation torque is applied. The sleeve’s outer cutting teeth expand and undercut into the base material. This results in a durable mechanical interlock with base material that functions in both cracked and non-cracked concrete.
