Review on iBOLT Aluminum 2.75 inch Double Socket Arm for 1-inch / 25mm / B Size Ball adapters - Ideal for Industry Standard Needs by Scott Channell

Probably works but has no internal spring to keep the parts connected and adjustable like a ram arm. It's just a cheap copy made by Chicom that doesn't work like a ram mount. Can't last long if you attach it to Ram ball mount. Without a connecting compression spring, the mount cannot clamp another ball when released. This was supposed to be for a portable speaker mounted on my bike and I'm going to take it off the boat before using this thing. The screw for the clamp parts doesn't hold together, if you lose a part you're screwed. Rather spend a few bucks more for a "real" Ram.
