An anchor is integrally connected to the backing of the frame assembly and has a central axis. The anchor has an inner conduit and a spring-loaded pin having a longitudinal axis and configured to be inserted into the aperture of the outer conduit of the mount along the longitudinal direction. The system includes means for connecting the anchor and mount in a rotatable relationship about the central axis.
