Sometimes you just have to! You were running your Ethernet cable and made an “oopsie”, severing your cable run. What to do? Maybe you were running your Ethernet cable, and found you did not have quite enough cable left to get from point A to point B. It would be an enormous waste of time and material to simply rip out the run! This is precisely what couplers were made for: Unforeseen circumstances and areas where you have to get the cable run to work, but otherwise have no way of resolving the issue.
