  • For austenitic variants add 'A' to end of part code (not including 6")
  • For slimline variants add 'S' to end of part code (not including 6", 13mm stack height only) 
  • For timber variants add '-TV' to end of part code (13mm stack height only)

 

Note: As with all types of friction hinges, friction cannot be provided until the slider moves, therefore when opening top hung vents to angles of 10° or less a separate device may be required to prevent the window from closing.
