Pushes sliding doors out of wall pocket


  • Available with two different spring forces
  • The model with 85 N is normally installed in most doors
  • The stronger version should only be chosen if the door doesn’t go smoothly, e.g. doors with a brush seal
  • Installed (invisibly) in the opening edge of the door


  • When opening the door the magnet buffer on the piston rod hits a counter plate and keeps the door open
  • To close the door, just press lightly against its edge and the integrated spring will push the door out of the wall pocket so far that the handle is accessible again

Function scheme release buffer

The release buffer is usually installed in the opening edge of the door leaf. This requires a corresponding boring in the door leaf.

Unless it is a door/frame of steel, the included counter plate has to be mounted as a counter part. It is needed for the magnet at the end of the piston rod that keeps the door safely in the open position.

In the wall pocket behind the opened door you only need a space of 25 mm for the release buffer.
