Ubiquiti UACC-RJ45-COUPLER-C6A | RJ45 Inline Coupler

A shielded Cat6A inline coupler sold in a 10-pack, for extending or joining ethernet runs inside a building without breaking the cable standard.

Why this one

• Shielded construction maintains signal integrity across the join, which matters when the cable run is close to electrical conduit or other interference sources.
• ANSI/TIA-568-D.2 compliance means the coupler meets the same cabling standard your Cat6A infrastructure is built to, so the join doesn't become the weak point in a high-speed run.
• At 16 × 16 × 31 mm and 7.1 g, each coupler sits flush enough to fit inside a standard wall cavity or patch panel enclosure without forcing cable bends.
• The 10-pack format suits a fit-out or structured cabling job where you need multiples on hand rather than ordering one at a time.

Good fit if you're extending Cat6A runs indoors — patching between two cable drops, reaching a switch that's slightly too far, or tidying up a cable run mid-install where a single continuous cable wasn't practical.

Worth considering something else if the join is outdoors or in a wet area — the RJ45-COUPLER-C6A-OUTD is rated for outdoor use and is the right pick for exposed or weathered runs.

What you'll also need

Cat6A patch cables with male RJ45 connectors on each side of the join, and a UniFi switch or PoE injector at one end to power any downstream device — the coupler itself is passive and carries whatever signal the cable is running.
