Klein Tools VDV826-704 CAT6A Pass-Thru Modular Plugs - Fast

Our review of the Klein Tools VDV826-704 modular data plugs finds a straightforward, professional-grade solution for installers who need reliable Category 6A terminations. The biggest reason to buy is its pass-through design that lets CAT6A and larger-diameter CAT6 cable jackets pass through the connector, ensuring a visible and consistent wire order and secure seating every time. For technicians who use a pass-through crimper and want PoE-compliant connectors that save trimming and waste, these plugs deliver predictable, repeatable results.

Key Features

• Pass-Through Design: Cable conductors pass through the plug so installers can verify correct wire order and achieve consistent terminations without guessing.
• CAT6A Compatibility: Designed specifically for Category 6A performance, these plugs support higher bandwidth installations per TIA/EIA-568-B.2 standards.
• Large-Diameter Support: The plugs accept larger-diameter or thicker-jacket CAT6 cables, reducing compatibility problems on varied cable types.
• PoE Compliant: Fully compliant with Power Over Ethernet and PoE+ so connectors work safely with powered devices.
• Solid and Stranded Wire: Eight position, eight contact design works with both solid and stranded conductors for flexible wiring options.
• Crimper Recommendation: Pairs with a pass-through crimping tool (VDV226-110 recommended) to trim flush to the end face and eliminate wasted material.

Who It's For

These modular plugs are best for professional network installers and advanced DIYers who terminate CAT6A or thicker-jacket CAT6 cable and already own or plan to use a pass-through crimping tool. The visible conductor pass-through makes verifying pair order quick, which speeds installations in wall plates, patch panels and inline couplers.

Casual users who rarely terminate cable, or anyone without a compatible pass-through crimper, should look elsewhere because proper installation depends on the correct crimping tool and some practice to get clean, secure terminations.

Pros & Cons
