## Questions & Answers

**Q: How firmly do the disks and the extension bar stay in place? Some sets rattle and squeak no matter how tightly bolted together.**
A: I've found that when using the dumbells, the disks and extension bar stay in place for the duration of the session. But when I go to do the next session a few days later, I almost always have to re-tighten the disks. But then again, I've found that to be the case for most of the sets I've worked with

**Q: Can the weight plates be sold separately?**
A: This will separate into it's different parts and if you wanted to sell each part you could do.
it is a good quality system

**Q: What is the thickness of the bars**
A: The thickness of the bar is approx 3-4 mm thick heavy and sturdy enough to take the weights supplied it works well

**Q: how long is the bar in total when connected?**
A: Approx 1 metre
