Black Box FMT631-R3-25PAK CAT6 Keystone Jack

Deliver cleaner CAT6 terminations with a keystone jack built for structured cabling standards. The Black Box FMT631-R3-25PAK is an RJ-45 female keystone designed to work with GigaTrue CAT6 cables and meet TIA/EIA-568-C.2 CAT6 requirements. With support for data transmission rates up to 250 MHz, it is aimed at installations where predictable performance matters across every port. The jack includes gold contact plating and phosphor bronze contact material, a combination chosen for reliable electrical contact and long-term durability in active network environments. Universal wiring and clear T568A/T568B labeling simplify deployment for field technicians and help reduce termination errors during large-scale rollouts. Its keystone form factor supports snap-in installation, making it suitable for patch panels, wall plates, and modular enclosures. Strain relief adds another layer of installation confidence, especially in environments where cable movement or repeated service access can stress terminations over time. For teams that value standards compliance and lifecycle reliability, this Black Box component offers more than a basic connector. It is a termination point designed to support professional cabling practices, keep ports organized, and reduce the hidden cost of rework in enterprise networks.
