Handy tools for saving wear and tear on the fingers while using Ideal wire nuts. 5 sizes, for the gray, blue, orange, yellow, and red connectors. I find these very helpful for getting the wire tightly twisted and fully inserted into the spring within the wire nut. (Be aware that they also make it easy to overtwist to the point that the wire breaks through the end of the nut.)

Designed for the “wingless” Ideal wire connectors: WT1, WT2, WT3, WT4, and WT6.
