Product overview
K87YW is a Dell PowerEdge 15th/16th gen 2U SFF B21 rackmount sliding Rail Kit. Rail kits are specific to chassis depth and rack post type, and the wrong kit will not mount. Give us the chassis model and rack depth and we will confirm the part before it ships.
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
The order is placed against K87YW, not against a description of it, so there is no room for a substitution you did not agree to.
Post type and depth matched
Square, round and threaded posts need different hardware; we confirm the rack before shipping the kit.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Questions buyers ask about this part
Is K87YW genuine and is the warranty intact?
Yes, new and sealed, with the Dell warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will K87YW 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.
