10m Cat 5 Network Cable

Ten metres goes through a doorway and into the next room, which is where most households actually need it: the router sits wherever the line comes in, and the console sits wherever the television is.

Long enough to route along a hallway skirting board without pulling at either end, short enough to coil behind a cabinet when half of it is spare. Moulded RJ45 plugs. A hundred in stock at three dollars.
