Round Panel Mount 5.5mm/2.1mm DC Barrel Jack Extension Cable

If you need to add a panel-mount connection for DC power, but don't have the time or ability to cut a custom oval or square hole, this Round Panel Mount 5.5mm/2.1mm DC Barrel Jack Extension Cable is the easiest and fastest way to panel-ify your existing project. The outer flange is 30mm in diameter, and the threaded part is 23mm diameter, so you can drill a 1" 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!
