Klein Tools VDV226-110 Ratcheting Data Cable Crimper - Pass-Thru Ease

In this review the Klein Tools VDV226-110 is evaluated as a shop-ready crimper for technicians and serious DIYers who terminate CAT3 through CAT6A cabling. The bottom line: this is a compact, well-built ratcheting crimper that combines a wire stripper, cutter and full-cycle crimper into one tool, and its Pass-Thru RJ45 workflow is the single biggest time-saver during repetitive terminations. For installers who value consistent connector seating and reduced prep time, the VDV226-110 delivers practical benefits without being overly complicated.

Key Features

• Pass-Thru Efficiency: Pass-Thru RJ45 support lets conductor ends extend through the connector for faster, cleaner terminations and reduced rework.
• All-in-One Function: Integrated wire stripper, cutter and crimper removes the need to carry separate tools and streamlines on-site work.
• Ratcheting Mechanism: The full-cycle ratchet guarantees complete connector termination to lower the risk of loose contacts and intermittent failures.
• Flush Trimming: Built-in trimming cuts conductors flush with the connector face to prevent unintended contact and maintain signal integrity.
• On-Tool Wiring Guide: A wiring diagram etched on the tool helps minimize wiring errors and speeds up correct pair placement for RJ11, RJ12 and RJ45.
• Comfort Grip Construction: Compact, non-slip handles reduce hand strain during long runs and make the tool easy to carry and store.

Who It's For

The VDV226-110 is ideal for network installers, telecom technicians and experienced DIYers who terminate CAT3, CAT5e and CAT6/6A cables regularly and need consistent, repeatable results. Its Pass-Thru compatibility and ratcheting action suit users who value speed and reliability when terminating multiple connectors in a single job.

Less experienced users who never work with Pass-Thru connectors or who perform only occasional terminations may find the feature set more than they need; also, if your workflow requires specialty connectors not supported by Klein Pass-Thru parts, look for a tool matched to those connectors.

Pros & Cons

Pros

• Solid build quality that feels durable in regular field use.
• Pass-Thru crimping and flush trimming speed up prep and reduce material waste.
• Ratchet mechanism ensures full-cycle termination and consistent crimps.
• Integrated stripper and cutter make it a compact, multifunction tool.

Cons

• Some users report inconsistent cutting of pass-through conductor ends on occasion, requiring a second trim.
• Only compatible with Klein Pass-Thru RJ45 connectors for the intended pass-through workflow.

Frequently Asked Questions

Can this tool crimp both RJ11 and RJ45 connectors?
Yes. The tool supports 4-, 6- and 8-position connectors including RJ11/RJ12 and RJ45 Pass-Thru connectors.

Does it work with CAT6A cable?
Yes. It is designed for CAT3 through CAT6/6A paired-conductor cables when used with compatible Klein Pass-Thru connectors.

Will it trim conductors flush automatically?
The built-in trimming function cuts conductors flush to the connector end face, though a small number of users have noted occasional need for a follow-up trim.
