Important: For Mortice applications we would always recommend a suitable lock or latch with a minimum backset measurement of 57mm to avoid rapping your knuckles on the door frame. This is the measurement from the edge of the door to the centre of the knob when fitted. You should consider increasing this measurement when fitting larger knob diameters or where the frame stop is greater than the normal 12mm.
