Black Box GigaTrue2 CAT6 Keystone Jack Unshielded (Green)

The Black Box FMT634-R3 is an unshielded CAT6 keystone jack made for installers who need dependable performance in gigabit networks. It handles frequencies up to 250 MHz, so file transfers, VoIP calls, and streaming video stay smooth even in busy office or campus environments.

This jack snaps into any standard keystone opening, which makes it a practical choice when you are populating patch panels, wallplates, or surface-mount boxes. A 110 punchdown connection on the back speeds up termination while keeping the wires secure. Because the wiring block accepts either T568A or T568B, you can match the scheme already in place without extra adapters or re-terminations.

Inside, phosphor bronze IDC contacts finished with tin resist wear from repeated punchdowns. On the front, 50-micron gold plating on the RJ-45 contacts maintains a reliable data path even after many insertions. The jack is backward compatible with CAT5e, CAT5, and CAT3, which helps when you are upgrading segments of an older network one piece at a time.

The green housing matches Black Box GigaStation2 wallplates and surface-mount housings, giving finished installations a clean, consistent look. Whether you are building out a new data center row or adding a single drop in a classroom, this jack provides a straightforward, standards-compliant solution.
