Attaching Thule Backup Box to Atera Strada DL3

[johneboy]

Hello,

I found a thread on here recently about putting a storage box onto an Atera Strada DL3 bike rack. In the thread had a post on it from someone saying they attached a Thule Backup Box to it (see picture below). Has anyone else managed this, and if so, would they be able to share instructions for how they did it please?

Many thanks in advance.

I’ve thought about it but was waiting to see someone else do it before buying the kit
