Perfect if your working on something at home and are bored... definitely not for the job site, fired!!!!!!! For lack of productivity.Good to know for the next time I'm using multiple pieces of electrical wire to hoist a load with a crane.That’s perfect next time I have a long weekend to sit and braid wire I’ll give this a try.It’s called a western union splice. They used it on telegraph wires. It’s still useful to pull a new wire with the old one.
