3.5" to 5.25" Drive Bracket

The Nippon Labs HDB-5250 is a plastic mounting bracket that adapts a single 3.5" hard drive or SSD for installation in a standard 5.25" drive bay. It is finished in black and ships with eight mounting screws for securing the drive and the bracket itself. This accessory targets system builders or upgraders who need to add 3.5" storage to a chassis that only offers 5.25" front bays.

Suits 3.5" drives in 5.25" bays only

The bracket suits anyone fitting one 3.5" HDD or SSD into an available 5.25" bay. It does not support 2.5" drives without a separate adapter, nor does it allow multiple drives in a single bay. Builders needing hot-swap trays, tool-less mechanisms or 2.5" compatibility should look at other solutions.

Single 3.5" drive per bracket

Each HDB-5250 unit accommodates exactly one 3.5" drive in one 5.25" bay. This one-to-one conversion ratio is the specification that determines whether the bracket matches the build plan.
