The NuTOne NA200QC Snap Down Connector used to replace a missing or defective connector with the NuTone NRS200 and NPS200 Intercom system and connects CAT-5 wire from volume control to the NuTone NM200 master.
It is designed for use with CAT-5 wire and has press-down wire locks that cut through the wire's insulation, so no wire stripping is required.
