Collection: RJ45 Couplers & Ethernet Line Extensions

RJ45 couplers extend Ethernet patch cords without cutting, splicing, or punch-down termination. Choose Cat5/5e, Cat6, or Cat6A options in shielded or unshielded designs for compatible wall plates, faceplates, and patch panels.

Use a female-to-female coupler when both Ethernet cables are already terminated. For bare cable, choose a keystone jack instead.
