I made this for a customer since there doesn't seem to be one. If you own one you know it has male threads and trying to install a Iris which also have male threads is next to impossible. The adapter is female-to-female and have raised embossed lettering to easily identify which end goes where as the threads are different.
I also do custom projects and one-offs at no cost to you. If you're interested please don't hesitate to reach out.
