The EZ-RJ45 system works because the crimper trims the pass-through conductors flush at the moment of crimp — and that trim is only as clean as the blade making it.
When terminations start showing ragged conductor ends, nicked strands, or connectors that need a second squeeze, the blades are telling you they're done. This OEM Platinum Tools replacement set restores factory-fresh trimming for a fraction of the cost of a new tool.

The set includes two replacement RJ45 blades and a replacement screw, compatible with Platinum Tools EZ-RJ45 crimper models 100044 and 100004C.
Swapping blades takes a couple of minutes with a small screwdriver, and the difference on the very next termination is obvious — clean flush trims, positive crimps, and connectors that pass certification the first time.

If the crimper earns its keep on your truck, keep a spare set of these in the case.
Dull blades don't announce themselves until you're mid-job with a punch list of failed terminations.
