SOLID wire cable so you can punch it down (you shouldn't punch down stranded cable!)
You can make solid wire modular cords yourself, but this has to be faster, easier and cheaper!
These are professionally made and tested (which is why there's a mod plug on both ends).
Connect a modular device to a 66 or 110 block, beanie it on to an existing wire... lots of other uses.
White/Blue and White/Orange pairs wired straight through to four pin modular plugs.
This CAT3 solid wire cord is wired with USOC wiring, with White/Blue on the middle pins and White/Orange on the outside pins.
Custom lengths available on request.
