Fire Extinguisher Pull Handle Mounting

I’m fitting a plumbed in Extinguisher system and want to fit the pull handle just above the boot release handle in the door surround.
I’v drilled through at the chosen position to find the area seems to be double skinned…can you tell me what goes on here?
It will be the same as access the boot release handle mechanism HELP please


Are you sure that’s the best place to fit it???

How would you/a marshall operate it if your car is up against a tyre wall/on its side? Much better to have it mounted on the dash, old boy

On my old Europa I had it mounted on the bulkhead between the seats. Short cable less chance of snags/failure (assuming the extinguisher is in the engine bay).


You have a point…will re investigate position as actress said to someone…
