This adapter suits the PlayStation 2 Expansion Bay with ethernet that has the sliding/moving metal brackets for IDE/Molex. This allows easy and secure installation of the widely available SATA adapter kit available for this.

The screws in the bracket are the two screws removed from the IDE connector, the other fittings and stand-offs should come with your SATA kit.
