ABSTRACT:
A handle set includes a handle assembly having an operator, a rose insert, and a shank having a bore. The rose insert has a central opening and a post. The shank is affixed to the operator and rotatably received in the central opening. A rotational stop is coupled to the rose insert. A spindle guide is slidably received in the bore and is slidable between a locked position and an unlocked position. A kick-off plate having a retention slot is coupled to the spindle guide. A centralizing cup having a single multi-function tang and a lock retention feature is mounted to the shank. The multi-function tang is configured for rotation along a rotational path, the rotation being limited by the rotational stop. The lock retention feature is positioned to engage the retention slot when the spindle guide is in the locked position to thereby retain it in the locked position.
