STEREN 50ft Ivory Telephone Extension Cord with RJ-11 Plugs - 6-Conductor Phone Cable Wire for Home & Office (BL-324-050IV) - Ideal for Extending Landline Phones, Fax Machines & Modems

Needed this to connect an all-in-one printer with fax to my phone line. It withstood all the pushing and pulling I subjected it to to wire it through the floors and walls of my house. Absolutely no problems with function. It also has a flat profile, which I found was less likely to fail at points where it was stapled to the beams in the basement.
