Product overview
This is the Tripp Lite SmartRack 18U mid-depth half-height rack Enclosure cabinet, order code SR18UB. Square-hole, round-hole and threaded posts each need different hardware, and the cage nuts are the part that goes missing. Tell us the rack and we will quote the fixings with it.
If the part is wrong for your platform we will say so and suggest the one that is, which is cheaper for both of us than a return.

What you get ordering this from us
Ordered by part number
Quoted and supplied against SR18UB specifically, so what arrives is what your build sheet asks for.
Fixings included in the quote
Cage nuts and screws are the parts that go missing, so they are quoted with the rails.
Post type and depth matched
Square, round and threaded posts need different hardware; we confirm the rack before shipping the kit.
Questions buyers ask about this part
Is SR18UB genuine and is the warranty intact?
Yes, new and sealed, with the Tripp Lite warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will SR18UB work in my server?
Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it: firmware revision and platform generation matter, and this is the check that prevents a return.
Do you accept purchase orders and quote at volume?
Yes. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.
