## Questions & Answers

**Q: Can be attached on the smallrig a6300 cage?**
A: yes of course, via the 1/4''-20 screw

**Q: What is the difference between rod clamp 1806 and 840? are the smaller threaded holes different in dimension? thank you.**

The different of the 2 rod clamps is that the rod clamp 1806 has a screw.

Hope that will help.

**Q: Do holes line up for mounting 2 of these to the back of my zoom h4n and allow me to attach it to the side of my dslr sholder rig?**
A: I thought the Zoom H4n only has one mounting hole on back?  So 2 would not line up...

**Q: Does smallrig make a 19mm version of this rod adapter?**
A: Hello,
This is Lawson from SmallRig Customer Service.
SmallRig doesn't have 19mm version of this rod adapter.
