Corbin Russwin
Retrofitting Corbin Russwin CK4200 grade 1 knobs
models prior to 1976
Locksets made prior to 1976 were made with the outside knob retainer rigid. To remove the outside knob on
pre-1976 locksets, remove one of the chassis screws completely, and loosen the other screw slightly. This
will allow the knob retainer to pivot out of the spindle and permit knob removal.
