Abstract
An example lockset generally includes a housing, a bolt, a turnhub, and a spindle. The bolt is mounted in the housing for movement between an extended position and a retracted position. The turnhub is rotatably mounted in the housing and engaged with the bolt. Rotation of the turnhub in a bolt-extending direction drives the bolt toward the extended position, and rotation of the turnhub in a bolt-retracting direction opposite the bolt-extending direction drives the bolt toward the retracted position. The spindle engaged with the turnhub, is operable to exert torque on the turnhub in the bolt-retracting direction, and is selectively operable to exert torque on the turnhub in the bolt-extending direction. The housing includes a pair of stops configured to limit rotation of the spindle to a predetermined angular range.
