USG Holder on a rack

I saw on the last Lawrence Services VLOG that there was a holder for the USG on the StarTech rack. I have a USG and I want to put it in a secure rack like that, where can I find this USG holder that works on the StarTech rack?

That is just a shelf, but it does work well for non-rack mount devices.

Thanks Tom, I thought you have a holder that was holding just the USG into the rack, but after I did more examination of the video of your rack , what I saw might be you Microtek 10gb switch. thanks Jim
