Got a Mystery Tool Number?
CT-, IT-, IR-, CP-, CD-, ET-, EM- prefixes? Those are ours. We can tell you exactly what you have.
For decades, Connector Microtooling Systems — formerly Graphic Datakits — supplied the aerospace and defense industries with precision connector tooling. We relabeled tools under our own prefix system. If your MRO kit is full of numbers that don’t match any catalog you can find, there’s a good reason: they’re ours.
You Have the Tool
It came in a kit. It has a number. But the catalog it came from seems to have vanished.
We Know What It Is
GDI and CMS used a proprietary prefix system for 30+ years. We have the complete database.
We’ll Look It Up For You
Send us the number. We’ll identify it, tell you what it does, and let you know if we can get you another one.
