摘要

A cylinder lockset (30) includes a chassis assembly (72) with sleeves (80) and (81). A pair of liners (36) and (48) are mounted on sleeves (80) and (81), respectively, and facilitate attachment of chassis assembly (72) with a door (260). A pair of spring cassettes (38) are mounted on sleeves (80) and (82). A pair of levers (42) and (54) are mounted on the sleeves (80) and (82), respectively, and operate cassettes (38) directly for spring return of the levers upon release thereof. A pair of posts (388) and (390) are mounted on liner 48 and are formed with score locator lines (412), (414) and (416) to locate the liner relative to a housing (74) of assembly (72). Liner (36) is formed with four mounting holes (356), (358), (360) and (362) which facilitate use of the liner with either a lefthand or right-hand door mode.
