📞 SIENOC 100 PCS RJ11 Plug 6P4C Phone Modular Telephone Cord Connector Adapter Crimp: Enhance Phone Connectivity with High-Quality Connectors! Review

Plug too small to power radar detectors. It vibrates and kills power. Other brand plugs work, but this one is too small. Also, there are no wire channel separators, so it's not easy to hold the wires while crimping.

I used these to add phone lines and phones to my old house. I use them on round and flat 4c phone cords. I was having trouble connecting the cores of the 4c cable to the locally available 6p RJ-12 crimps. I've used some to connect to the RJ-12 6p6c jacks which I have with no problems.

With a suitable crimping tool, these connectors provide an easy way to terminate 4-wire CAT3 telephone cables with a plug. I've found them to work well with both flat and round phone cords. However, with round cables, the cores must be correctly positioned for correct polarity before being inserted into this connector for crimping. properly aligned and inserted into the connector and then crimped. The connection is then strong and compact. These connectors are inexpensive.
