This convenient RJ-12 or RJ-11 Telephone Round Panel Mount Plug is perfect for adding a panel-mount connection to your telephone-interfacing projects. No need to waste time or effort cutting a custom-shaped hole, simply use a common hole-saw or bit to create a 30mm diameter hole in your wood, plastic or metal. Then, just unscrew the plastic nut, insert the plug, and re-attach it to your existing phone kit. You'll have a pass-through RJ-12 jack in no time!

Note that RJ-11 and RJ-12 use the same connector! The difference is that RJ-11 has only 4 wires inserted, while RJ-12 has all 6. So you can use this adapter for either. Note that this is not compatible with RJ-45 Ethernet Jacks or plugs; those are bigger and have more contacts.

This adapter fits snugly onto panels ranging in thickness from 16mm to a few mm. It is an ideal solution for adding a port to your project enclosure, thanks to its sturdy design and discreet plastic lip that covers the drill hole.
