## Questions & Answers

**Q: We already have a zip line in the backyard but need to replace this piece. Can we add this piece without taking the line down?**
A: Yes it sets on the line and works great.

**Q: Will this work for a 3/16" steel cable zip line?**
A: yes

**Q: Is this suitable for a 1/2 inch cable? Our zipline has a 1/2 inch cable but thr max cable size listed on the trolley says less than 12mm**
A: I don't think so.  The throat narrows and won't allow the 1/2" cable to go through. This is made the same width as the rollers so you can't use too big a cable.
