These components are trim pieces located at the entrance of a vehicle, covering the area where the door frame meets the floor. Typically constructed from metal or plastic, they often feature branding or decorative elements. For instance, many General Motors vehicles manufactured during the mid-20th century had these protective and aesthetically pleasing additions bearing the mark of a prominent coachbuilder.
The presence of these components served multiple purposes. Functionally, they protected the underlying rocker panel from wear and tear caused by ingress and egress. Aesthetically, they added a touch of refinement to the vehicle’s interior, signaling quality and attention to detail. Their connection to a historically significant automotive body manufacturer further enhanced the perceived value and prestige of the automobile.
