1. A knob assembly for a door comprising: a spindle configured to extend through said door approximately perpendicular to a planar surface of said door; a latch in communication with said spindle and extendable from an edge of said door, said latch being actuated in response to rotation of said spindle; an inner knob portion fixedly secured to said spindle, said inner knob portion including a first surface and a cavity extending inwardly from said first surface, said cavity being defined by a side wall; an outer knob portion freely rotating on said spindle, said outer knob portion including a second surface facing said first surface, said outer knob portion including a first section having a first mating edge and a second section having a second mating edge abutting said first mating edge to form an abutment line; a first lug projecting from said second surface of said outer knob portion for engagement with a first notch formed in said side wall of said inner knob portion, said first and second sections of said outer knob portion being selectively movable in opposing directions along said abutment line to positively move said first lug into engagement with said first notch for enabling rotation of said spindle when said outer knob portion is rotated to move said latch from a normally latched position to an unlatched position; and a second lug extending from said second surface of said second section for engagement with a second notch formed in said side wall of said inner knob portion.
