## Questions & Answers

**Q: what is the square body made of, not the ruler, but the body itself - I suspect soft alloy?**
A: The bodies of the tools that slide on the steel ruler are made of aluminum.  I am not the manufacturer.  I am a consumer who bought one.  I like it.  It is very durable and accurate.

**Q: Which measurements? Image shows metric markings but text states graduation in 1/32 inches.**
A: Mine has no Metric measurement definitions.

**Q: What is the maximum thickness of the ruler it works with. Can it adjust to a four foot ruler?**
A: If the four foot ruler has the same notch opening in it, it would work.  There is an insert that fits into the notch

**Q: Made in where ?**
A: Made in China, where else?
