ABSTRACT:
A lockset 20 includes an interior knob 24 mounted on an insert 26 and an exterior knob 62 mounted on an insert 64. A rose liner 30 and a cover 58 are mounted on the insert and provide a spaced bearing support for an interior assembly including knob 24. A rose liner 70 is mounted on insert 64 and combines with a security shield 146 and bearing 148 to provide a spaced bearing support for an exterior assembly including knob 62. Knob 62 is assembled with insert 64 through dimples 164 and projections 168 to allow slippage of the knob on the insert upon the application of excessive force without destruction of elements of lockset 20.
