Network/Server Cabinet rails/shelving

[xrapidx]

I have an old 18U network cabinet I'd like to repurpose as a server cabinet in my office.

Where can I find similiar 18U railings to mount at the back to allow for shelves?

Linkqage?

Popped them a mail - but could only find 27U. I suppose I could take a grinder to them.
