This is a table designed to fit the R1200GSA BMW Panniers. It is made from stainless steel and locates on the `L` projections at the corner of each pannier so it does not move.
There is also a flange either side, which carries the R1200GSA logo, and this adds strength to it and stops it from bending.
It is made from stainless steel so will not rust and it is easy to keep clean.
I have found it very handy (I use one myself) and it fits nicely into a pannier.
