The ICC CAT6 RJ45 Inline Keystone Coupler features a female-to-female 8P8C design for extending Ethernet patch cords through wall plates, patch panels, or surface mount boxes. Built with PCB technology, it supports consistent signal transmission and reduces insertion loss. This feed-through coupler exceeds ANSI/TIA-568-C.2 standards for CAT6 connecting hardware, supporting frequencies up to 250MHz while minimizing crosstalk and return loss. Its compact rear footprint allows for high-density installations, and the UL-listed housing ensures compliance in commercial and residential structured cabling systems.
