There seems to be two distinctly different design of hdd tray. One design has 3.5 hdd directly mounted on the tray via 4x #6-32 screws en face. Dell video mentions: for Dell Slim ECS1250 or the Dell Tower ECT1250.

The other design has 4x “HP style” side mount blue grommet which lets the 3.5” hdd slide into a caddy of the tray.

This more elaborate design allows a slim odd to be mounted on top of 3.5 hdd. Dell video mentions: for
Dell Pro Tower QCT1250/ QCT1255, Dell Pro Tower Plus QBT1250, Dell Pro Slim QCS1250/QCS1255, or the Dell Pro Slim Plus QBS1250.
