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.

A system for attaching door lock trim roses on inside and outside faces of a door, comprising: a mounting chassis comprising an outside member and an inside member, said members each having two opposed cylindrical arc portions together with means for joining said outside member to said inside member to secure said mounting chassis to the door with both members firmly positioned against the outside and inside faces, respectively, of said door; a hollow inside trim rose and an outside trim rose interchangeable therewith, both trim roses having same means of attachment to said mounting chassis, each said trim rose having two diametrically opposed pips projecting radially inwardly to a given radial extent, said pips lying in close proximity to an edge of said trim rose which contacts a face of said door after installation of said trim rose thereon; detent means on said outside member of said mounting chassis for receiving the pips of said outside trim rose and for thereby securing said outside trim rose against the outside face of said door; and groove means on said inside member of said mounting chassis for receiving the pips of the inside trim rose, said groove means comprising at least two undercut sites, opposedly spaced on opposedly spaced cylindrical sector arcs on the periphery of a projecting portion of the inside member, undercut to a depth less than the radial extent of said pips of said inside trim rose, adjacent an edge of the inside member which is in contact with the face of the door when mounted thereon, to capture the pips and to maintain the rose against said inside face of said door and under a constant elastic stress when said rose is installed on said mounting chassis.
