## Long description

The ROLINE RJ-45 Keystone Modular Coupler Cat.6 shielded silver is a keystone-style, shielded coupler designed to join two RJ-45 Cat.6 twisted-pair cables. With an all-metal housing and 8 contacts connected 1:1, it provides a compact means to extend or repair Ethernet runs while maintaining shielding continuity for improved signal integrity. The grey/silver finish fits standard patch panels, wall plates, and keystone inserts.
Advantages
The shielded metal housing reduces electromagnetic interference and helps preserve Cat.6 performance across the connection. The keystone format allows easy snap-in installation into compatible panels and plates. The 1:1 wired 8-contact connection ensures straightforward passthrough of transmit and receive pairs without re-pinning.
Suitable for

How to use
