Convert back and forth between various types of phone plugs with high-quality phone adapters from CableWholesale. We know that not all phones require the same kind of connectors and jacks, which is why these low-cost adapters are an essential for any networking or communications professional. CableWholesale stocks RJ11, RJ12 and RJ45 adapters — all of which come backed by a lifetime warranty for worry-free purchasing — so you can get the most out of any port without a total rewiring. We also offer wholesale and bulk phone adapters that are great for large, commercial jobs.



Our RJ45 phone adapters are always some of the most useful. For example, you can use an RJ45 telephone line connector to plug two phones into one phone jack or to add a fax machine to your configuration without the need to install a whole-new plug. These adapters come in options for RJ45 and RJ11/RJ12 for a variety of applications. You may also want to use one of our inline telephone couplers in applications where you need to join two telephone lines together, including two 8P8C, RJ11/RJ12 and RJ45 telephone lines. An ADSL filter is also a great option for anyone looking to filter out unwanted noise and interference from DSL or phone connections.



CableWholesale also carries essential phone wiring supplies that you can use to create a clean, professional networking room or office. Use one of our punch-down blocks to connect voice and data network wiring and other telephone punch-down cabling or pick up super-affordable mounting blocks that allow you to snap in 66 blocks easily and quickly. If you aren’t sure which phone adapters and accessories are best for your unique needs, don’t hesitate to
