The box should be on my new Elektroveloziped. But the porter did not fit, because he was too wide - or the included mounting hardware to narrow. As an engineer, once one sees then that part more closely, and notes that the ground is absolutely flat. Therefore, you can see the holes and put differently - and now the mounting straps are longitudinally. Of course I did so the return claims forfeited - who cares? It works, the box is not distorted and can be closed properly. The side clips pull the lid on the pan reliably. Let's see how long do these plastic lever. Otherwise, the container makes a stable impression. I am happy.
