These are Brand New Genuine Dell OEM Recline Stands that fit the Optiplex 7460, 7470, 7480, 7490 and 7400 (8th through 12th Gen) models.  Of the Dell stands that fit these machines, this is my personal favorite - when wall mounting is not an option.  I've seen enough broken screens on these machines that the adjustable height stands, in particular, make me cringe - and the standard stands are just boring.

...they'll also fit the similar 'T' models, but these models have a black back; so, you may not like the color mis-match since these stands are silver.

And then there's the rubber feet.  Personally, I feel that these should be standard on ALL of the Optiplex models and not just matched with these Recline stands, but that Dell's call.

These arrived to me as large packages of two.  If you buy two, I will ship in this large package, which will have to ship via FedEx / UPS.  If you buy just one, then I can ship it in a more Postal friendly package size.

...and ships to you immediately!  :-)
