We intend to replace all four fixed port lights in the coming months .
We see that the stainless cover / fixing plate is held with screws , not bolted through and there appears to be a “rubber “ gasket. Doesn’t seem to be silicone ? .
Can anyone advise what material was used by Amel?
is there anything we should be aware of before attempting this project ????
Please see photo below by way of illustration:-
Thanks again for all support, very much appreciated.
