## Questions & Answers

**Q: Are these terminals made of tinned copper?**
A: Yes, they are made of tinned copper and thick enough to do job. It also uses polyolefin, double wall, adhesive lined tubing.

**Q: Is there ribbs on the inside of the barrel or is it smooth?**
A: They are smooth. There's a tab on the inside to stop the wire from going all the way through. If crimped right and heat shrunk they won't pull apart

**Q: Are these made in the USA?**
A: No there made in China.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good set, fit my needs.
*by T***N on June 3, 2025*

Nice set. Love the heat shrink stuff. I don’t have to add any extra tubing to them.

### ⭐⭐⭐⭐⭐ Excellent quality, great price
*by E***C on August 10, 2024*

I took a chance and bought these for use on a sailboat that lives in salt water. Normally I buy Ancor connectors since they are the absolute highest quality available but they are also extremely expensive. The metal connectors in this kit are not quite as heavy duty as the Ancor ones but they are close and the adhesive lined, heavy duty heat shrink is identical. For the price these connectors are exceptionally high quality and a much better value than Ancor for most electrical tasks.If you need some high quality marine rated electrical connectors I would highly recommend these.

### ⭐⭐⭐⭐⭐ Very handy kit to have around.
*by K***C on March 6, 2025*

Seems to be good quality and a wide variety of sizes. Purchased for one small job and have gone back to the kit many times since on other projects.
