Extron CTU RJ-45 Die (part number 101-025-01) — the factory replacement die set that puts a worn Extron CTU 45 crimp tool back into spec.

A crimp tool frame outlasts its die. The ratchet and handle keep working long after the machined jaws have rounded off, and the first symptom is rarely an obvious failure — it is an intermittent link, a pin that seats shallow, a shield ferrule that no longer bites. Rather than buying a whole new tool, fit this die. It is the same Extron-engineered, precision-machined solid steel die the CTU 45 ships with, so crimps come back to full accuracy and repeat the same way plug after plug.

Key Capabilities

• Direct factory replacement for the die in the Extron CTU 45 RJ-45 crimp tool (part 101-024-01).
• Solid steel, precision machined by Extron — not a generic aftermarket jaw.
• Also retrofits Extron CTU 300 four-in-one crimp tool frames and BNC crimp tool handles, so one spare can cover more than one tool on the truck.
• Suits modular RJ-45 plugs of shielded and unshielded types, keyed or non-keyed.
• Changed in the field: back out the top and bottom retaining screws, slide the old pair free, slide the new pair in, close the tool gently to capture them, then refit both screws.
• Top and bottom halves are a matched pair and stay together going in.

Where It Is Used

This is a consumable for teams that terminate their own twisted pair: AV integration crews wiring classrooms, boardrooms and lecture halls, in-house facilities and IT groups maintaining campus or hospital AV distribution, broadcast and control-room technicians, and rental or staging shops whose tools see far more cycles than any fixed install ever will.
