The brand had serious air, the dimensions (a little painful to find on their site) are perfect for my use:
Inside dimension of the loop for the ref 54573:
Horizontal Pouch Cove b [mm]: 22
Vertical opening loop c [mm]: 23
Handle diameter d [mm]: 6
The advantage is that it is robust and light with the materials used (aluminum).
normally designed for outside, we'll see if it holds up better than those I had bought in the supermarket and who eventually rust everywhere.
the mechanism made a good impression with a well placed price :)
