Collection: Keystone Couplers

Ethernet couplers provide a simple, cost-effective way to extend Ethernet connections without additional cable runs. Available in inline, feed-through, and bulkhead configurations, our RJ45 couplers connect two patch cables to create a longer link while maintaining signal integrity. Shielded and unshielded options support CAT5e, CAT6, and CAT6a applications including PoE++ pass-through for high-power devices.

Inline Couplers

Inline RJ45 couplers provide a straight-through female-to-female connection for extending patch cable runs. Available in shielded nickel-plated housings for EMI protection and unshielded FR-plastic housings for standard installations. Snap-in designs fit keystone panels and wall plates, while HD couplers support high-density patching environments. Compatible with CAT5e, CAT6, and CAT6a with PoE++ pass-through on select models.

Feed-Through and Bulkhead Couplers

Feed-through couplers mount through enclosure walls, providing a sealed RJ45 connection point for outdoor and industrial applications. IP67 and IP68 rated models feature waterproof and dust-proof FR-nylon construction for harsh environments. Bulkhead couplers offer panel-mount connectivity with weatherproof sealing for outdoor enclosures and equipment cabinets.

Specialty Couplers

Our coupler lineup also includes RJ45 splitter couplers for passive network tapping, rollover couplers for RJ11/RJ12 voice applications, and MIG-style press-fit couplers for permanent installations.
