I've got one, but without the clamps.
It's only trim. It sits on the cabin lining where the mast comes through the cabin roof. It makes for a nicer view if you are in your bunk looking upwards.
It's removable to make it easier to get the mast in and out.
I wondered that too, but how do you get at the catches to do it up, and why is it so thick?
