Leviton 47604-CR construction ring. These rings are installed prior to hanging drywall and become the base platform for installing Series 100 Structured Media (SMC) units such as the 47604-CRI (sold separately). Once the drywall is installed and cut, the back panel is snapped into the ring and the ring becomes the attachment point for the cover panel. These are intended for people who need a replacement ring or who have kits without the ring included.
