An elegant ringed mortice knob on a concealed fix. Polished brass finish. Diameters: Knob diameter: 50mm Rose diameter: 70mm Projection: 72mm Grub screw spindle fixing.
These door knobs are unsprung and we recommend fitting these with our heavy sprung latches to ensure a smooth operation and that the knobs return to the correct position after turning.
The minimum length of latch required is 3"/76mm which allows for space between the door knob and the door frame enabling you turn the handle and not catch your hand in the frame.
