From the Anvil Polished Brass Ball Door Knob set 83630
Heavy solid Ball knobs are designed for use with mortice only.
For best results the door knobs should be fitted a minimum of 3 inches from the edge of the door to avoid catching your knuckles. We recommend a heavy duty tubular latch 18299 in 4 or 5 inch case depth.
Supplied with matching screws and 8mm bar spindle.
Knob size 47mm diameter
