  • The UnderCut Anchor consists of an Anchor Sleeve and a Flange Bolt.
  • Anchor sleeve and bolt length have to be matched to the hole depth required and to the panel bracket chosen.
  • The anchor sleeve is expanded to its original dimension by inserting the screw to a controlled depth,so that the sleeve sits snugly against the undercut section of the hole in the facade panel.
