Important Info Before You Buy

  • For use on inward opening doors only
  • Roller bolt night latches are used in place of a standard "Yale" style night latch, in multi-place occupancies i.e. flats with communal front door.
  • Conforms to current fire regulations concerning means of escape in event of fire
  • When you pull the lever down (clockwise) on the lock case the roller bolt extends in to the keep on the frame to keep the door closed.

    When the lever is in the Horizontal position (shown in the image) the roller bolt is withdrawn an the night latch is in open position

  • Roller bolt is withdrawn from outside and by quarter turn of key in one direction and engaged by turning the key a quarter turn the other direction
  • This means the door can only be locked by someone physically turning the key or handle hence you can't get locked out just by the door closing
  • Suitable for doors up to 54mm thickness
  • Comes with cylinder, cylinder ring and two keys
