Review on Enhancing Efficiency with Jonard BW 532 3 Wrench Tamperproof Screwdriver by Abdalla Galloway

This tool is used to access the 'secret' parts of the phone company's protector or 'Network Interface Box' in your home so you can rewire your phone wiring. . It opens the outer and inner NIU bays. The device is well made and works as it should. It's just a hex wrench with a small hole in the middle that attaches to the handle. It runs on an NIU installed by AT&T at my home. This comes in very handy when a 25 year old phone repairman keeps visiting my house to fix my DSL line (again and again) and keeps forgetting to close the NIU bay doors. The purchase is worthwhile.
