主权项

1. A lock assembly, comprising:
an elongated housing extending along a longitudinal axis between a first end and an opposite second end, said elongated housing defining a hollow portion between said first and second ends; a plug positioned in said hollow portion of said housing, said plug including an elongate body extending between a first end portion and an opposite second end portion, wherein said body defines a key slot in said first end portion for receiving a key to rotate said plug relative to said housing; a latch operating mechanism extending from said second end portion of said plug; an end cap configured to couple said operating mechanism to said second end portion of said plug so that rotation of said plug rotates said operating mechanism, wherein said second end portion of said plug is configured to slidably receive said end cap in a keyed orientation from a direction transverse to said longitudinal axis for securement to one another in an interfitted relationship, wherein said interfitted relationship prevents said end cap from moving along and around said longitudinal axis relative to said plug; and an alignment pin housed in said plug, wherein said alignment pin selectively prevents movement of said end cap in said direction transverse to said longitudinal axis; and wherein said alignment pin is removably engaged with said end cap.
