“Great for when you forget to put an insulator on a wire, or realize you need more than you thought. Not sure why they need to be so expensive, but they're still much better than having to cut and splice.”
“These are perfect to have on hand when installing high tensile for the times your wire is a little close to a source of ground. Just twist it on and its isolated and you dont need to take the strand down to slip on a solid tube.”
