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

probably works but doesn't have an internal spring to connect the parts and adjust like a rammer's hand. It's just a cheap Chicom knockoff that doesn't work like a ram mount. Can't stop when you attach it to the ram ball mount. Without a link compression spring, the bracket 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 won't stay together, if you lose a part you're screwed. Spend a few more bucks for a "real" Ram.
