Vszerda 40 PCS Gigabit RJ45 Coupler Female to Female (Black)

40-Pack Gigabit RJ45 Couplers

This 40-piece pack supplies female-to-female inline couplers that join two Ethernet patch cords into a single longer run. Each unit supports gigabit data rates and is compatible with Cat5 through Cat8 cables. The nickel-plated contacts and shielded PCB construction resist corrosion and maintain signal integrity. No drivers or configuration are required for installation.

Installers extending existing runs

Technicians who need to bridge two short cables in home, office or lab environments will find the snap-in retaining clips provide a secure, tool-free connection. The couplers are not compatible with keystone jacks or RJ11 telephone plugs, so buyers needing wall-plate termination or voice-grade wiring should look at dedicated keystone modules or RJ11 adapters instead.

Verify cable types and jack styles

Confirm that both cables use standard RJ45 plugs and fall within the Cat5 to Cat8 range before ordering. The couplers cannot be used with keystone-style wall plates or with RJ11 telephone cords, so ensure your existing patch leads and termination hardware match the inline female-to-female format.
