The 3D H-screw is a very stable connection between two handles which is made by screwing.
  • makes it possible the alignment of the handrails
  • boltable dowel-connections without
  • annoying tension of the elements


  • The holes are pre-drilled with a 13mm wood drill on the front side (both sides).
  • The metal sleeve is screwed into one side as far as possible with a bus key, so that the metal surface ends with the cut surface of the handrail.
  • The counterpart is screwed in with a special bolt (screw-in height).
  • Then the two hand steps are screwed together to the zero point.
  • Now the handles can be turned a maximum of one turn further.
  • establish best position and rework easily if neccesary.
