1. A lockset, comprising:
a housing;
a bolt mounted in the housing for movement between an extended position and a retracted position;
a turnhub rotatably mounted in the housing for rotation about a rotational axis and engaged with the bolt, wherein rotation of the turnhub in a bolt-extending direction drives the bolt toward the extended position, and wherein rotation of the turnhub in a bolt-retracting direction opposite the bolt-extending direction drives the bolt toward the retracted position; and
a spindle engaged with the turnhub, wherein the spindle is operable to rotate about the rotational axis and 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; and
wherein the housing includes a pair of stops configured to abut the spindle to limit rotation of the spindle to a predetermined angular range.
