Abstract:
A roseless trim for a mortise or tubular lock includes through bolts on a bolt circle of less than one inch (25.4 mm). Spindle hubs with a curved slot allow at least one of the through bolts to pass through the spindle hubs. A tubular lock embodiment uses arms with a cutout. The arms function as through bolts when screws attach the arms to mounting plates on opposite sides of the door. Each handle is attached to a corresponding handle base with a bushing. The handle base and small diameter bolt circle cooperate to provide the appearance that the handle extends directly into the door without a rose, escutcheon or any other attachment structure at the base of the handle.
