Hope that will help. Lucia SmallRig **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.
