I just need the knob. Hard to find. Found a pack of 4 on eBay for $12. They go on the laptop holders. Otherwise it's all security pin and keyed knobs that I don't need. I'll keep looking. Thanks for the heads up on it.I thought I had gotten it on Amazon but I looked at my order history and didn’t see it on there. Not sure where I got it.
Might be able to find the part number on ram mounts website and then look it up.
