• 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• When the lever is in the Horizontal position (shown in the image) the roller bolt is withdrawn an the night latch is in open position
• Roller bolt is withdrawn from outside and by quarter turn of key in one direction and engaged by turning the key a quarter turn the other direction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
