## Description

If you need to add a panel-mount connection but don't have the time or ability to cut a custom oval or square hole, this **USB C Round Panel Mount Extension Cable** is the easiest and fastest way to panel-ify your project. The adapter is about 30mm in diameter, so you can drill a hole in your wood, plastic or metal with a common hole-saw or bit, no special shapes or filing required. Un-screw the plastic nut, insert the plug and re-attach. Ta-da! Now you have a USB C jack and USB C plug for connecting any cable.

It's designed to easily attach to a panel up to 16mm thick (or 0.625"), or as thin as a few mm. Perfect for adding a USB C port to your project enclosure! Adafruit like this plug in particular for its solid body and 'forgiving' plastic lip that hides the drill hole.
