⚡ At a Glance
  • Mounting Stability: Standard hole spacing and screw holes ensure firm alignment and secure attachment
  • Best for: DIY PC builders, system upgraders and IT technicians needing reliable 2.5" to 3.5" conversion
  • Not ideal for: Enclosures without standard 3.5" bays or proprietary mounting systems

Two metal brackets convert 2.5-inch drives to 3.5-inch bays with standard screw alignment. Supplied mounting kit helps secure drives for everyday desktop use.


Secure, rattle-free mounting – thanks to standard hole spacing and bottom screw holes

Brackets have standard cutouts and screw holes that align with 3.5-inch bay fixings, and additional bottom screw holes hold drives firmly in place. Metal construction reduces flex and keeps the drive seated under vibration.

Drives stay stable during transport and operation, preventing loose connections and noise. Safer fixation reduces risk of accidental dislodging when moving or servicing a PC.

Better cooling under load – with ventilation holes on bottom and sides

Heat dissipation holes are present on the bottom and both sides of the bracket, allowing airflow around the drive. Metal body also conducts heat away from the drive surface.

SSD and HDD temperatures are helped during sustained workloads, lowering thermal throttling risk. Improved airflow supports longer, more reliable operation in compact cases.

Quick, straightforward installation – thanks to the supplied screws and screwdriver

Package includes two mounting brackets, 16 screws and one screwdriver sized for the screw heads, enabling direct attachment of 2.5-inch drives into the brackets and then into a 3.5-inch bay. Size of each bracket is 12 x 10 x 1.5 cm.

No need to source extra hardware or tools, making upgrades faster and simpler. Compact bracket dimensions fit most standard desktop internals without obstructing neighbouring components.
