I purchased this adapter to connect a Novatron flash head to a boom arm I recently aquired. It works great. The connection is very solid and secure even with an umbrella attached.
It took me a good while to get it to connect to the light stand. Once I got it on propperly it won't budge.
I use these to mount old Novatron heads, and Speedotron Mw3 heads to normal light stands.
It is wonderful for attaching smaller diameter lighting devices to large stands. Great Product!
