160 and 160S: with detachable frame fixture


Used for windows and glazed doors together with ASSA espagnolette, which has transmission device.


  • 150S and 160S are type-approved as child-safe restrictor according to building regulations outlined by the Swedish National Board of Building, Planning and Housing.
  • Applicable when the key has been removed.  
  • Operated with the espagnolette handle.
  • With the handle in closed position, friction holds the sash in the desired airing position.
  • To reduce wear on sash and hinges, the casement stay slips when overloaded.
  • With the handle in open position, the sash can be moved freely.
  • The friction increases with the opening angle.


  • 160S have a locking bolt, which limits the opening to allowed airing position with regard to child safety (max 100 mm opening).
  • To open past this position, the detachable key must be in place and turned.
  • When the sash is opened, the key is turned before the sash reaches the locking position.
  • The locking function returns automatically when the sash is closed and the key is removed. It also returns by turning the key back manually when closing the sash.
  • Use the plate ASSA 4575 to have permanently freed locking function (included in manipulation fitting ASSA 4570).
