The "Kelislipped" Anchor is installed in the usual manner. The nut can be wrench tightened by hand without risk of rotating the anchor within the cured resin.

To remove a "Lefty", a removal tool or double nut is threaded on the anchor. When driven by a Hi Power Impact Wrench in a clockwise direction (which would normally tighten a bolt), the L.H. thread will instead back out.
