Towards the end of the WOC 2016 show in Vegas we stumbled upon a small booth for the Industrial Cord Connector. This simple system was conceived of and developed by a woodworker who wanted a way to keep his tools connected to the extension cord while moving around a jobsite, and that protected the connection and prolonged the life of the cord ends. This connector system is also designed to accept after-market plug ends.The video below shows how the system works. It's made in the USA and a set sells for $25 on Amazon.
