The only problem is that Amazon has the wrong picture posted, and has ignored multiple requests to correct it.This unit does not have a hardwired modular cord at one end. That is a different Fluke banjo product. This unit has a modular plug at both ends, and you can plug it inline with a working telephone set to break out the four conductors of the RJ-11 plug.This unit also offers the benefit of small holes in the terminal tabs, which allows the skinny alligator clips of a phone test set to clip on securely.I am very happy with this unit and there is no justification for the low rating that one reviewer has given it. That reviewer is unhappy because the picture was wrong. He should have just returned his purchase and gotten the one he wanted, which I'm sure Amazon would have done at no charge given the incorrect photo on this page.If you verify the model number on the Fluke site you will see that this one is equipped with a modular plug on both ends. It works fine in situations where that is what is desired. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Invaluable Modular Adapter for my test set *by M***Z on Reviewed in the United States on November 6, 2018* I purchased this Fluke Modular Adapter for use with my Fluke test set. It is of very good quality and works well. If anything happens to mine, I will definitely be getting another one. This is well worth the price. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars A must have tool to troubleshoot POTS lines *by J***R on Reviewed in the United States on June 28, 2021* Recently I have been getting multiple calls to repair the POTS lines to Fax / all in one printers I hadn’t used my previous banjo for quite some time and couldn’t find it. These are great to make sure dial tone is available I was able to use this a couple of times and now I found my other banjos :-) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/17135386-fluke-networks-10210101-4-wire-in-line-modular-adapter-k](https://www.desertcart.gr/products/17135386-fluke-networks-10210101-4-wire-in-line-modular-adapter-k) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-23*
