550350 (TOL31) Cat6 RJ45 Inline Coupler Keystone Jack

The 550350 (TOL31) is a high-performance Cat6 RJ45 female-to-female inline coupler keystone jack engineered for fast patch panel distribution, wall plate terminations, and network cable extensions. Designed to fit all standard keystone wall plates, surface mount boxes, and modular patch panels, it allows technicians to connect two pre-terminated Ethernet patch cables seamlessly without punch-down tools.

Built with gold-plated contact pins and a flame-retardant ABS housing, the 550350 supports gigabit network speeds up to 1 Gbps / 10 Gbps over Cat6 cabling with high signal clarity and minimal insertion loss. It provides an efficient solution for office network expansions, server rack patch bays, and structured cabling deployments.
