From The Anvil Ebony Beehive Mortice/Rim Knob Set

Our knobs come unsprung. An attractive Beehive knob set in a rich and dark ebonised finish. Each set comes complete with detachable roses in a stylish antique brass and fixing screws. The GRUB SCREW should locate on the ''V'' in the shaft and not on the threaded part. For best results the centre of the knob should be a minimum of 3" from the edge of the door. Heavy Duty latches 4" or 5" are recommended for maximum efficiency.
