The Netshoe

The Netshoe provides a quick fix for ethernet cable plugs that have lost their tongues.

Update - 06-25-22: I've made slight changes to the tongue section to provide more accurate printing.

Due to many improvements implemented over the years, ethernet cable plugs don't lose their tongues as often as they used to. But if you would like to make a semi-permanent repair to any broken RJ-45 cable plugs without the cutting, stripping, and crimping needed to install a fresh plug, this might work for you. It may also help if you need a way to lock a plug into its jack, because these things generally don't come loose accidentally. I have them in use all over my house.

No two broken ethernet plug tongues leave a nub with exactly the same shape or size, but my experience is that they almost never need any special treatment to work with the Netshoe. The tongue side of the plug must have no remaining guard material so that it is perfectly flat
