Drive Bay Conversion

The Nippon Labs HDB-35525 bracket lets a 3.5" hard drive or SSD fit securely into a standard 5.25" drive bay. It is built for system builders who need to add mechanical storage without sacrificing larger bay space.

Physical Bay Constraint

The adapter only works when the chassis provides a 5.25" front-access bay and the drive itself is a 3.5" form factor. Cases that lack 5.25" openings or that use tool-less rails incompatible with screw mounting cannot use this bracket.

Single Drive Capacity

Each bracket accommodates exactly one 3.5" device, so a second drive requires a second bracket and a second 5.25" bay. Buyers planning multiple drives must verify their case has enough available bays before ordering.

Questions about this item

Is this bracket the only version available for fitting a 3.5" drive into a 5.25" bay?

Yes, the HDB-35525 is a single conversion tray that adapts one 3.5" HDD or SSD to a standard 5.25" drive bay.

What does the 3.5" to 5.25" conversion actually do inside my case?

It lets a 3.5" drive sit securely in a larger 5.25" bay so you can use empty optical bays for extra storage.

Does the bracket use any special interface or just standard mounting holes?

It uses the standard 5.25" bay screw pattern and includes eight screws plus a pair of mounting strips for a secure fit.
