RJ45 Coupler ROLINE Model 21.17.3114 Category 6 Shielded, 25 pcs/Box

ROLINE RJ45 Coupler Model 21.17.3114 is a Category 6 shielded inline adapter supplied in a box of 25 pieces. It is designed to join two RJ45 cables while maintaining Category 6 performance and providing metal shielding to reduce electromagnetic interference. The coupler supports quick network extensions, temporary joins and on-site repairs without affecting signal integrity in structured cabling environments for commercial and residential networks.

Advantages

The shielded Category 6 design preserves high-speed data transmission characteristics and helps reduce noise from external electromagnetic sources. The inline form factor allows fast, tool-free connections between two RJ45 terminated cables. Supplied in a box of 25 pieces, the product is convenient for installers and maintenance teams who need multiple replacements or spares for patching and repairs.

Suitable for

• Extending network runs by joining two RJ45 patch cables
• On-site temporary repairs of Ethernet links in offices and homes
• Structured cabling tasks where Category 6 performance must be preserved
• Environments with potential electromagnetic interference where shielding is beneficial

Key specifications

• Category: Category 6 (Cat6) performance
• Shielding: Metal shielding for EMI/RFI reduction
• Connector type: RJ45 inline coupler (female to female)
• Package quantity: 25 pieces per box
• Typical use: Inline joining of two terminated RJ45 cables

How to use

Insert a terminated RJ45 cable connector into one side of the coupler and a second terminated RJ45 cable into the opposite side until each clicks into place. Ensure both cable terminations are properly seated to maintain Category 6 contact alignment and shielding continuity. For best results, use with properly terminated Cat6 patch cables and avoid repeated insertion/removal cycles that may wear contacts.

Usage recommendations

Use the coupler in dry, indoor environments or within appropriately protected enclosures. When joining shielded cables, ensure cable drain wires or shield continuity are correctly connected on both ends to preserve the shielding effectiveness. Keep spare couplers available in installer kits for fast replacement during maintenance.
