HP Fax Cords
Hewlett-Packard insists that their fax machines work best with two-conductor line cords, instead of the more common four-conductor cords. They say, "You must use a cable that has only two copper leads."
VoIP service providers such as Vonage recommend these cords, too, particularly when people have both a conventional analog phone line and a VoIP line and the analog line is interfering with VoIP.
We stock them in five lengths, but if you need one in a special size (even 137 feet), we can make it for you and get it shipped out quickly.
