You've got pre-terminated Cat6 cables and need to connect them through a patch panel without re-terminating or pulling new runs. These couplers close that gap in seconds. Snap one onto your blank patch panel, plug both cable ends in, done. No punch-down tool, no crimping kit, no fiddling with tiny connectors before the office opens. Twelve per pack covers a small office or a single rack build in one go. Works with the Ubiquiti UACC-Rack-Panel-Patch-Blank-24 blank panel. If your cabling is already terminated and you just need a clean pass-through link, this is the fastest way to sort it
