All-in-one RJ45 crimper

The Klein Tools GJ673-1P-UK is a single hand tool that crimps, strips, cuts and terminates Ethernet cables. It accepts pass-through and standard RJ45 connectors across multiple categories plus RJ11 and RJ12 plugs. The kit includes the crimper and two spare blades for extended service life.

Adjustable presser bar

A rotatable knob on the presser bar switches the tool between CAT6 and CAT7 crimping positions, removing the need for separate dies. This single adjustment covers CAT5, CAT5e, CAT6, CAT6a and CAT7 connectors in both shielded and unshielded versions.

25-pin capacity with spare blades

The tool handles 25-pin connectors and is rated for mild steel up to 10 mm. Two replacement blades are supplied so the cutting edges can be refreshed without buying a new crimper. It is not suited for coaxial or fibre terminations.

Questions about this item

What does the 25 pin count mean when I am terminating cables in the workshop?

The kit includes 25 pins so you can crimp multiple RJ45 or RJ11/RJ12 connectors without running out of contacts during a job.

How does the adjustable knob control which cable categories the tool can crimp?

Rotating the knob switches the presser bar between CAT5, CAT5e, CAT6, CAT6a and CAT7 modes, letting one tool handle all those connector types.

What physical space does the crimper need to fit in a tool bag or on a bench?

The compact design with non-slip grip and rotatable knob allows easy storage in a standard tool bag or drawer.
