How to Manage AC/DC Power Adapters in a PDU in a Datacenter? [closed]

We have servers in a datacenter’s cabinet. We have a PDU (Power Distribution Unit) to power up these servers.

We have a few devices which need to be plugged in with an AC/DC power adapter. These power adapters are kinda bulky and block multiple outlets. And they also never quite hang out right and always seem to be half unplugged. Anyway, we’re now running out of outlets, so we need to free those that are blocked by these bulky AC/DC power adapters. We’re thinking of just buying a short extension cord, but that feels wrong somehow: do we just leave the power adapter hanging loose at the end of the cord?

There must exist a device we’re not thinking about. Is there such a device? Or is the extension cord the best way to manage that?
