Abstract
A walk-in freezer door system has a doorjamb with sheets of metal covering a body of thermal insulation. A door is mounted to the doorjamb. A deadbolt housing is mounted to the outside of the doorjamb with a deadbolt mounted for reciprocal movement within the housing between a door locked and a door unlocked position. A handle is rotatably positioned inside of the doorjamb from which a shaft extends into the deadbolt housing and into operative association with the deadbolt. A longitudinal portion of the handle shaft is made of a low thermal conductive plastic. A keeper is mounted to the door in a position to receive the deadbolt with the door located within the doorjamb.
