RJ-45 Keystone modulárna spojka VALUE 21.99.3003

The VALUE RJ-45 Keystone Modular Coupler 21.99.3003 is an unshielded keystone coupler for extending Cat.6 twisted pair cables. It features a plastic housing in black and provides a compact, 1:1 connection between two RJ-45 connectors with eight contacts to maintain standard Cat.6 wiring.

Advantages

The coupler supports Cat.6 cabling standards and preserves a straight 1:1 pin mapping across all eight contacts. Its keystone form factor fits into standard wall plates and patch panels, and the plastic housing provides a lightweight, low-cost solution for extending Ethernet runs. The black color allows discreet installation in typical home and office environments.

Suitable for

• Extending Cat.6 Ethernet cables without reterminating ends
• Use in keystone wall plates and patch panels
• Quick temporary or semi-permanent network joins in home and small office setups

How to use

Insert the coupler into a compatible keystone wall plate or patch panel opening if required, or use it as an inline connector by plugging one RJ-45 terminated Cat.6 cable into each side. Ensure both cables are fully seated to maintain correct contact engagement. The coupler does not require tools to connect but may require a keystone punch or snap-in installation when mounted into wall plates or panels.

Recommendations

The coupler is suitable for Cat.6 unshielded installations; avoid using it where shielded (STP/FTP) continuity is required. For permanent, high-performance links consider professionally reterminating cables or using a dedicated patch panel to minimize insertion loss and maintain optimal signal integrity.
