Abstract
A system for attaching door lock trim roses on inside and outside faces of a door, has a mounting chassis with inside and outside members, each having outwardly projecting portions with opposed cylindrical sector arcs. Fasteners join the outside member to the inside member to secure both members against the outside and inside faces of the door. Interchangeable hollow inside and outside trim roses have at least two inwardly projecting pips close to a door contacting lip of the trim rose. Detents on the outside member of the mounting chassis receive the pips of the outside trim rose and secure the outside trim rose against the outside face of the door; and grooves on the inside member of the mounting chassis receive the pips of the inside trim rose. Grooves consist of at least two undercut sites on the periphery of a cylindrical portion of the inside member and extend axially from a face of the inside member in contact with the inside face of the door a maximum distance at a first end and a minimum distance at a second end, the undercut sites acting as portions of a screw thread in which the pips of the trim rose are engaged for fastening the trim rose.
